If you try to inspect elements located inside an IFRAME that was loaded from a
different domain, not satisfying the same origin policy, Web Inpector in recent
WebKit nightly builds cannot show style information. Works in Safari 4.0.4.

Load the test page at:
http://web.t-online.hu/fdsoft/iframe/

Then try to inspect the blue text on yellow background.

WebKit nightlies no longer can show the proper colors and instead show these
error messages in the console:
Error dispatching: getStyles
Error dispatching: getComputedStyle
