# Frame 1 of the sticky repaint pair. The scroll frame is scrolled to y=60 and
# the sticky element is stuck to the viewport top, but Gecko painted it at its
# natural (unstuck) position and reports no previously-applied offset, so
# WebRender applies the whole 60px itself.
#
# Paired with sticky_repaint_2.yaml, which is the same visual state after Gecko
# repaints having baked the 60px into the coordinates it emits. Since
# `previously_applied_offset` now only feeds display-list-builder normalization,
# both frames must normalize to the same unstuck geometry, intern identical
# values, and leave the tile valid.
