Marker rectangles are not updated when doing an accelerated-composited scroll

Summary
Marker rectangles are not updated when doing an accelerated-composited scroll

Document stores a list of marker rectangles that are used for things like Find. They rely on painting to get invalidate and recomputed. However, if you do an overflow-div scroll with composited layers, then there may be no painting so nothing updates the rectangles.

Testcase To show the bug, do a Find, and Find Again in Safari, and then scroll the div. The rectangles are left in the wrong places.

I am able to reproduce this bug in Minibrowser based of WebKit ToT (
268538@main
) and it shows 'highlight' container / rect for hidden content despite not scrolled.
