do less on abort if not done
Abort() was resetting state when it didn't need to, and possibly also not resetting as much of it as it needed to. I'm not sure if this is a completely correct fix but it passes some WPT tests.

Prevent infinite recursion when upgrading custom elements
<!-- Please describe your changes on the following line: -->
The spec and tests were out of sync when I implemented #25410 and I mentioned I'd have an extra detail to attend to if whatwg/html#5126 landed; it did, and I did, and a couple test cases pass.

Update CanvasRenderingContext2D fillStyle and strokeStyle only when required
So far fill and stroke style updates have been sent to the canvas paint
thread by `SetFillStyle()` and `SetStrokeStyle()`. This resulted in
fill/stroke style updates not being considered by the canvas paint
thread between the latest call of `SetFillStyle()`/`SetStrokeStyle()` and
the drawing operation (e.g. fill or stroke).
This issue is solved by making `SetFillStyle()` and `SetStrokeStyle()`
update the local canvas state and propagating the state to the canvas
paint thread along with the drawing operations that require it.

fix#24869
The first run of this will spit out a lot of new test failure metadata, of course.
Run eventsource wpt tests with Python3
I deliberately changed the CI to run the WPT tests using Python3 to see if it works.
Even if we don't want to change the CI right now, the first commit with only the python requirements update can be merged.

Implement HTMLMenuElement
<!-- Please describe your changes on the following line: -->
Per spec, "The menu element is simply a semantic alternative to ul to express an unordered list of commands (a "toolbar")." We already have the CSS for it in user-agent.css, and this gives us the interface object.

Expire cookies on lookup
<!-- Please describe your changes on the following line: -->
Cookies were rarely, if ever, expiring; this caused tests that used max-age=0 as a cookie deletion method to have cookies they shouldn't have had.

Add microtask checkpoints to script elements and custom elements
Servo had a microtask checkpoint at the end of running a script, but there was also supposed to be one at the end of HTML-parsing a script element before Javascript-parsing the script itself, and there were supposed to be checkpoints immediately after the call to a custom element constructor. This adds those, passing all cases of one WPT test file.

Make File objects roundtrip through FormData
FormData.append now only creates a new File object if it needs to file-wrap a blob or set a filename, and not when appending an existing File with no filename override. The hardest part here was reading the specification in a way that matched browser behavior.

Let custom element registry know about picture tag

This replaces one WPT failure with another, but the previous one failure was preventing multiple cases from running, and now only one of those cases fails (due to #24993).

Add initial scrolling support to layout_2020
This adds very early scrolling support to layout_2020. Only the root element scrolls for now, but the idea is to continue to polish this.

Update the WebGL2 test expectations
It seems the WPT test runner/updater has some troubles picking up successful test results, so I've regenerated the `ini` files manually for the WebGL2 tests.

Return the highest priority error from the descendant instead of return the very first one
The test failed because we didn't return the highest priority error (which is network error in this case).
As Manish mentioned in https://github.com/servo/servo/issues/25436#issuecomment-571065323, that's because we're using the Promise.all trick to signal loads.
If we can avoid relying on Promise.all, maybe we don't need to do a complex logic like this; instead, ideally, we should always finish the module load immediately when we hit network failure so that we don't even need to do the `max()` comparison.
