I’m trying to use WebKit’s audits panel to remove some unused CSS in a fairly complicated webapp I’m working on. It loads forever, and it’s not a bug in WebKit because it works well on other sites. All resources have finished loading – there are no pending requests that I can see, and I think JavaScript should be idling too…
This happens both in Chrome and Safari (latest), OS X 10.7.
Any ideas?

Since recently, canary Chrome allows you to stop running audits, but the best option possible would be coming up with a publicly available test case URL that can be accessed by developers, and filing a respective bug using http://new.crbug.com (mention “DevTools” in the summary line and set the “Feature-DevTools” label if possible.)
