# Frame 1 of the external-scroll-offset repaint pair. Gecko has scrolled the
# frame to y=60, but has not repainted yet: the display list is still the one
# painted at scroll 0 (external-scroll-offset zero) and the whole 60px is carried
# as an async scroll delta.
#
# Paired with eso_repaint_2.yaml, which is the same visual state after Gecko
# repaints at scroll 60 - the 60px moves from the async delta into
# external-scroll-offset, and every coordinate inside the scroll frame shifts by
# -60 to match. The display list builder normalizes that shift back out, so both
# frames must intern identical values and leave the tile valid.
#
# The content deliberately spans the whole scrollable range and the scroll delta
# is smaller than the viewport, so a normalization failure leaves content
# visible (just misplaced) and dirties the tile, rather than pushing everything
# off-screen and producing a vacuous pass.
