Created attachment 243618 [details] Demo Works well in Safari 8.0.3 (10600.3.13) but already broken in r176637. See attached GIF for the steps to reproduce. The expected behavior is to show the selected JS file (min.js) when switching back to the Timeline.

Fixed by the tab based user interface as of: http://trac.webkit.org/changeset/183342
