Xianzhu Wang 41a8646dd0 Bug 1626771 [wpt PR 22626] - Fix fragment data under overflow clip under multicol, a=testonly
Automatic update from web-platform-tests
Fix fragment data under overflow clip under multicol

This fixes fragment data LogicalTopInFlowThread for overflowing contents
under clip under multicol. Previously the overflowing parts created
phantom fragments as if they were overflow:visible. Now the overflowing
parts are under the last fragment of the clipping element. They will be
painted correctly when they scrolls into the container clip rect.
