--- Comment #4 from Brian Burg <bburg at apple.com> ---
Analysis:

Test.html finishes loading. Our load event listener calls InspectorFrontendHost::loaded() which makes the  inspector focus, which makes the webpage window unfocus and resign first responder. This causes style recalc, and we have sync instrumentation underneath it (this should really be more async btw). The instrumentation generates an event to be dispatched to the frontend. The dispatcher hasn't been told that the window is loaded yet under InspectorFrontendHost::frontendLoaded. It's not safe to eval scripts due to the sync style recalc upthread, so the dispatcher suspends and tries again on another run loop turn.
