WPT tests for position-try-fallbacks should use canonical ordering.

Spec 1 defines "Canonical order: per grammar," so the serialization should
re-order <try-tactics> entries in order of their appearances 2.

Depends on D221988

Correct scroll snap area for fragmented blocks.

A DCHECK would fail if a node got block-fragmented, since we'd add the
LayoutBox for it multiple times. Only add the LayoutBox when at the last
fragment.

Secondly, calculate the correct bounding box for such blocks.
PhysicalBorderBoxRect() would give the rectangle in the stitched
coordinate system (where we pretend that nothing gets fragmented, but is
just laid out into one tall strip). Use QuadsInAncestor() instead.

Deal with edge case in the code from bug 1891335.

Apparently we might not create a subdoc frame for unless it's
inside .

Let's treat it as fully hidden.

Remove crossdoc variant from nested VT test

It's a very flaky test, and the scenario is already tested in the
mpa-serialization suite.

Improve base-select initial focus

This patch checks to see if the selected option is focusable before
trying to focus it when opening the picker. It also chooses a fallback
option to focus in the case that the selected option is not focusable.

Revert "[EncodedTransform] Add WPT for owner of the frames"

This reverts commit 449367647a200e6ac6306a4c901db92f08f261b8.

Reason for revert: suspect of flakiness

Original change's description:

[EncodedTransform] Add WPT for owner of the frames

Implement a WPT to test the logic ensuring that only frames previously read by the same owner can be written.

Additionally, moved function appendToBuffer to a helper.
