- Open inspector - Go to Sources panel - Hit Pause (top right) - Do something to force JS execution - Hit Resume Expected: things work Actual: after Resume is pressed, Pause button is not rendered.
Yeah, I too observed some text disappearing from DOM elements. I reverted those lines from r140296 - and everything works again for me. Note, that this regression is not specific only to Web Inspector. I changed component to Layout and Rendering.
That's weird since the patch in bug 104997 should only be doing more layouts then before. If you could make a reduction, that would be helpful. Feel free to revert if this is blocking work.
The patch was rolled out in bug 107857, I'm going to dupe this against that bug. *** This bug has been marked as a duplicate of bug 107857 ***
