How to reproduce: 1. go to http://docs.fuelphp.com/ 2. click on "TABLE OF CONTENTS" 3. hover over the links (copied from downstream bug: http://crbug.com/117356) The issue is that we are not repainting the link as we should (the CSS is updated if you query it). This is due to us not updating our cached repaint rectangle. Patch forthcoming.

Did this regress at some point?

(In reply to comment #2) > Did this regress at some point? Yes, this is a regression from bug 75568 (as we don't have a layer in this case, we need to make sure we properly cache our updated size which we did not do in this case).

I tweaked the test a bit to avoid having platform-specific text dumps. Tested on Chromium-linux + SnowLeopard (both Chromium & Mac)
