# Frame 2 of the sticky repaint pair; see sticky_repaint_1.yaml.
#
# Same visual state as frame 1, but Gecko has repainted with the 60px of sticky
# offset baked into the emitted coordinates and reported back as
# previously-applied-offset. The display list builder subtracts it again, so the
# sticky frame and its contents normalize to the same unstuck geometry as frame
# 1 and WebRender re-applies the same 60px at frame time.
