The "blur" and "focus" events on IFrames are not getting fired.
The URL points to a test case that uses IFRAME.contentWindow to attach to the events. It works well on Firefox.
I've also tried it with IFRAME, IFRAME.contentWindow.document and IFRAME.contentWindow.document.body with no results. Actually, when using IFRAME.contentWindow, the "focus" is fired when the page is loaded, but further "blur" and "focus" are not fired after it.
Confirmed in 418.9 and ToT.
This should be retested after r18610 landed.
I can no longer reproduce the problem with the linked test case.
Confirmed this has been fixed in a locally-built debug build of WebKit r18703 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8L127).
