Bug 1838911 [wpt PR 40597] - Revert "View timeline: Handle offscreen stickiness.", a=testonly

Automatic update from web-platform-tests
Revert "View timeline: Handle offscreen stickiness."

This reverts commit 8164954aefce51cc59f95da80c0acce888a1bc0b.

Reason for revert: Causing flaky failures, e.g. https://ci.chromium.org/ui/p/chromium/builders/ci/mac11-arm64-rel-tests/20525/overview.

Original change's description:
> View timeline: Handle offscreen stickiness.
>
> A view timeline subject inside a position:sticky box can get "stuck"
> from any of the four CSS offset properties (left, top, right, bottom)
> during any of the named view-timeline ranges (entry, contain, exit) or
> even while it is entirely outside the viewport.
>
> ViewTimeline::CalculateOffsets previously assumed that stickiness occurred only when the subject was fully contained by the viewport.
> This change implements the more general solution.
