Martin Robinson 501cb2637d Bug 1888621 [wpt PR 45425] - compositing: Send entire scene's scroll offsets when sending WebRender display lists, a=testonly
Automatic update from web-platform-tests
compositing: Send entire scene's scroll offsets when sending WebRender display lists

WebRender does not preserve spatial tree offsets when updating the
spatial tree. Updating the spatial tree of a pipeline can also
update the spatial tree of child pipelines. This change ensures that
WebRender always gets the scroll offsets of the entire scene when
modifying display lists in a way that may rebuild the spatial tree.

Fixes #31807.
