> a lot of the data on the site actually comes from MDN
Eh... not really.
The feature support matrix (as linked on CanIUse) comes from the browser-compat-data repo. Here's the HTML element's source data: https://github.com/mdn/browser-compat-data/blob/main/html/el...
This doesn't contain the testing and usage info that CanIUse cites for support, though, just which browser versions included which features.
CanIUse also points to their own repo, which contains a lot of data: https://github.com/fyrd/caniuse
But I can't find an easy entry point to find where they're getting the numbers for a specific element. The data on there seems to be primarily for features.
So the more precise question is, where is CanIUse getting HTML element testing and usage numbers from? Because that seems to be the issue.
