Summary Web Inspector: TypeError when reloading page with Debugger sidebar panel open

Repro steps: 1. Go to http://www.nihilogic.dk/labs/tetris/ 2. Open resources sidebar, create a few breakpoints in tetris.js 3. Open timelines sidebar 4. Open debugger sidebar, select a breakpoint 5. Reload with Cmd+R a few times Occasionally, there will be this error: ResourceSidebarPanel.js:214: JS ERROR: TypeError: null is not an object (evaluating 'representedObject.parentFrame.mainResource') ResourceSidebarPanel.js:252: CONSOLEAPI ERROR: Didn't find a TreeElement for a representedObject associated with the ResourceSidebarPanel. The resource in question is a Resource instance for tetris.js. It seems that it may be loading in some unexpected order wrt. the main resource. Attached is a stack trace. The bug seems independent of restore strategy; I found it when rewriting restore on reopen/reload, but it reproduces in trunk as well.
