 # Expectations for SlimmingPaintInvalidation feature
 
-# Rebaselined because of different clipping behavior, sometimes more accurate
-# (e.g. about css clip), sometimes less accurate (e.g. when clip has transforms)
-# which doesn't matter.

-# Rebaselined: We use FrameView::x() and FrameView::y() which are integers to
-# generate FrameViewpreTranslation, but the old path uses offsets in the layout tree.
-# paint/invalidation/repaint-during-scroll-with-zoom.html
-
-# Rebaselined because we expand local paint invalidation rect to whole pixels
-# before mapping it to backing so it may cover extra pixels causing incremental
-# invalidation not applicable.
