| Tests paint invalidation of the scrollbar (to repaint tickmarks) on document change when there are text match markers. |
| Passes if the tickmarks are updated on document change.<br> |
| <!-- Currently paint invalidation of main frame scrollbar is not tracked, |
| so use a frame to show the invalidation of tickmarks. --> |
