This is the kind of boring feature that can end up saving huge amounts of developer time. Z-indexing in CSS is kind of annoying and I've seen projects just detach dialogs from their normal position in the DOM entirely to get around stacking errors before.

Minor question:
> - There is only one `top-layer` but it can have many children. Last opened === current element on top.
Is this true? The spec says:
> The top layer is an ordered set of elements, rendered in the order they appear in the set. The last element in the set is rendered last, and thus appears on top.
I'm still playing around with `dialog` elements, so you may well be right, I'm just having trouble finding the actual spec rules about what happens when there are multiple dialogs and they're being simultaneously manipulated.

Worth noting that there is a polyfill (https://github.com/GoogleChrome/dialog-polyfill), but that the polyfill comes with some fairly large limitations, specifically that they don't advise dialogs be used as children of elements with their own stacking context.
This is reasonable, but also... my first thought when I originally ran into `dialog` was "finally I can stop worrying about which of my elements create new stacking contexts!" -- so it does decrease the usefulness quite a bit.

Here's a long conversation on it from 2016: https://github.com/whatwg/html/issues/1929
It has something to do with interfering with automatic focus on the dialog when it pops up as a modal.

In the meantime, NoScript[1] frequently avoids them entirely by just showing the page contents with no JS at all, and Kill Sticky[2] cleans up the ones that require JS to show you the content you actually want.
