testcase

Use "Find in page" in that text case to search "text" and highlight the single search match. Then scroll the overflow node: The highlighted text does not moved with the content of the overflow node.

Extracting this from bug 163911, as that seems orthogonal.

testcase

This is an extended testcase, showing that dynamic scrolls of the main frame or of the subframe make the selection disappear (contrary to desktop).

So to summarize:
- User scroll of a the main frame with hightlighted text works.
- User scroll of a subframe with hightlighted text does not update the position of the highlighted text.
- Programmatic scroll of the main frame or a subframe with hightlighted text makes the selection disappear.
