REGRESSION (307212@main Safari 26.x): flex column padding excluded from
scrollHeight
https://bugs.webkit.org/show_bug.cgi?id=316902
rdar://179376053
Reviewed by Elika Etemad.
This fix an issue introduced in
https://webkit.org/b/286753
https://github.com/WebKit/WebKit/pull/57545
A flex column with overflow:auto and top/bottom padding stopped including
that padding in scrollHeight when its items overflow the content edge.
307212@main introduced scrollableContentAreaOverflowRect() returning the
padding box instead of the content box when no overflow is recorded yet.
Return flippedContentBoxRect() instead, matching the pre-307212
behavior and the helper's name.
It also adds a WPT test to catch it next time.
