If there are 100 warnings, you have to sit there and wait for all of them to render and scroll up. This bogs down processing of the initial surge in events when the inspector opens, and makes it feel unresponsive at first. If possible we should avoid doing sync layout work when handling messages in the initial few seconds, especially if it's redundant. We should batch the rendering using requestAnimationFrame and/or sending them over protocol from the backend.

This is going to be mitigated by bug 155629 "Web Inspector: Adding a new console message shouldn't modify DOM when the console log is hidden". Besides, I'm going to use requestAnimationFrame batching.

The attached reduction works pretty smooth. I believe all the mentioned issues were addressed in bug 155629. If it isn't the case, feel free to reopen this bug. *** This bug has been marked as a duplicate of bug 155629 ***
