Summary UI frozen when the debugger is paused

Reported 2008-07-15 10:22:32 PDT
In certain cases, the inspector UI can be frozen while the debugger is paused. I've found one way to reproduce this, there might be others. The test uses /loaded|complete/.test(document.readyState) to simulate DOMContentLoaded. It's a test widely used for earlier versions of WebKit. Steps to reproduce: 1) Open the testcase 2) Open the inspector 3) Try to show/hide the console. Actual behaviour: The console panel doesn't open Expected behaviour: The console panel should open

New ones : 1) Open the testcase 2) Open the inspector 3) Enable the script debugger (the page reloads) 4) Try to show/hide the console.

Comment on attachment 22945 [details] Proposed patch r=me This seems like the right fix unless we can change the design so fireTimersInNestedEventLoop is no longer needed. I'm still hoping we can do that some day.
