Bug 192487 – Web Inspector: Move TreeOutlineGroup coordination out of TreeElement

• Component: Web Inspector
• Status: RESOLVED FIXED

[Matt Baker]

TreeOutlineGroup should respond to SelectionDidChange events from TreeOutlines it tracks, rather than the current intrusive approach where TreeElement calls back into the group.

I did notice some unrealted selection issues (not sure if it relates to something that's already been filed).

* STEPS TO REPRODUCE:
1. open WebInspector
2. show the Resources tab to any JS file (starts the FormatterWorker)
3. open WebInspector2
4. set a breakpoint in WebInspector2 on `WI.showRepresentedObject
5. do something in WebInspector to trigger that pause (e.g. switch tabs or select something in a navigation sidebar)
6. switch call frames in WebInspector2 to the last frame of the Page, and then switch again to the FormatterWorker's Idle frame
7. step over
 => the first frame of Page and FormatterWorker's Idle frame are both selected

An assertion is also thrown on TreeElement.js:538:23

I removed the assertion, which was added in https://webkit.org/b/192353. We already check that TreeElement.prototype.deselect is called by the TreeOutline on behalf of the SelectionController after an item is deselected.
