Some questions about RAM, BT and Firefox
I just don't know what else I can do. I compared Chromium and Firefox in html5test.com, got same result. All browsers says they doesn't support H.265. I turned off HW acceleration, nothing changes. I installed ffmpeg-libs and other codecs from Fedora wiki. Nothing changes. Videos are same vp9 in browsers. I spent all day googling but nothing helpful.

widevine problem?
What does https://html5test.com/ say for h.264, VP8, VP9 and Theora support? What does it say for aac, Opus, Vorbis and mp3 support?
-
is there a way to get surround sound working on firefox?
You can use this website also https://html5test.com is really helpful with more datails
- Opera GX on Windows 10 home ver. 22H2 unable to play short clips on Discord, Twitter/X, etc.

H265 Browser compatibility
If I go on html5test.com, no matter which browser I use, H265 support is not enabled and I couldn't find any article online that explains why -- what am I missing here?
- Why is there only Firefox-esr on Debian?

Flatpak Opera h264 issue
When I install Opera via flatpak and do html 5 test it says h264 is not supported, what can I do?
-
Opera GX(98.0.4759.64) Windows, videos on Twitter sidebar as well as various streaming sites don't work
What does https://html5test.com/ say for h.264 and aac support?
-
chromium cannot play some video formats
The h264 test page shows the same output in both chromium and chrome, and i can play the same formats from this page
- [Discussion] Chase completely nonfunctional on 13.5. Both the app and website are incompatible. Ridiculous

Show HN: Dropflow, a CSS layout engine for node or <canvas>
To reply mostly with my WPT Core Team hat off, mostly summarising the history of how we've ended up here:
A build script used by significant swaths of the test suite is almost certainly out; it turns out people like being able to edit the tests they're actually running. (We _do_ have some build scripts — but they're mostly just mechanically generating lots of similar tests.
A lot of the goal of WPT (and the HTML Test Suite, which it effectively grew out of) has been to have a test suite that browsers are actually running in CI: historically, most standards test suites haven't been particularly amenable to automation (often a lot of, or exclusively, manual tests, little concern for flakiness, etc.), and with a lot of policy choices that effectively made browser vendors choose to write tests for themselves and not add new tests to the shared test suite: if you make it notably harder to write tests for the shared test suite, most engineers at a given vendor are simply going to not bother.
As such, there's a lot of hesitancy towards anything that regresses the developer experience for browser engineers (and realistically, browser engineers, by virtue of sheer number, are the ones who are writing the most tests for web technologies).
That said, there are probably ways we could make things better: a decent number of tests for things like Grid use check-layout-th.js (e.g., https://github.com/web-platform-tests/wpt/blob/f763dd7d7b7ed...).
One could definitely imagine a world in which these are a test type of their own, and the test logic (in check-layout-th.js) can be rewritten in a custom test harness to do the same comparisons in an implementation without any JS support.
The other challenge for things like Taffy only targeting flexbox and grid is we're unlikely to add any easy way to distinguish tests which are testing interactions with other layout features (`position: absolute` comes to mind!).
My suggestion would probably be to start with an issue at https://github.com/web-platform-tests/rfcs/issues, describing the rough constraints, and potentially with one or two possible solutions.

It also helps that there are tests

Making Web Component properties behave closer to the platform
You can see how Mozilla tests the compliance of their built-in elements in the Gecko repository (the ok and is assertions are defined in their SimpleTest testing framework). And here's the Web Platform Tests' reflection harness, with data for each built-in element in sibling files, that almost every browser pass.

We're building a browser when it's supposed to be impossible
We have our own test suite (orginally derived from the test suite of Meta's Yoga layout library [0]) which consists of text fixtures that are small HTML snippets [1] and a test harness [2] that turns those into runnable tests, utilising headless chrome both to parse the HTML and to generate the assertions based on the layout that Chrome renders (so we are effectively comparing our implementation against Chrome). We currently have 686 generated tests (covering both Flexbox and CSS Grid).
We would like to utilise the Web Platform Test suite [3], however these are not in a standard format and many of the tests require JavaScript so we are not currently able to do that.

What new CSS and JavaScript features can we expect soon? Or is it all unexpected?
The metrics are based on the passing rate for the web-platform-tests (WPT) project, the automated test suite for web standards. The completion rate is categorised as either stable, or experimental. There is no definition of what experimental entails, presumably features that are behind experimental flags are included. Stable is better to go off in any case.

[AskJS] MSE quality resources
Depends on what you are trying to achieve. You can run WPT MSE https://github.com/web-platform-tests/wpt/tree/master/media-source and WebCodecs https://github.com/web-platform-tests/wpt/tree/master/webcodecs tests manually to learn by doing.

Rookie question: How do I know I am making progress with my JS learning?
Manually running the tests in Web Platform Tests should keep you busy.

Browsers Running Old JS Engines
Not sure what you mean? I referred to Web API's, which generally means Web platform API's; that is Web platform API's tested by Web Platform Tests https://github.com/web-platform-tests/wpt.

State of CSS
If you want CSS to be the same across browsers then help implement CSS tests and file bugs
https://www.w3.org/Style/CSS/Test/Overview.en.html
https://web-platform-tests.org/
better specs are great, but tests will actually find the edge cases and lead to more convergence.
