Bug 163403 – Web Inspector: Dragging to delete a Breakpoint should never trigger a ContentView change

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Summary:
Dragging to delete a Breakpoint should never trigger a ContentView change

Steps to Reproduce:
1. Inspect http://bogojoker.com/shell/
2. Set a breakpoint in easySlider.min.js
3. Set a breakpoint in facebox.js
4. Show Debugger Tab
5. Select the facebox.js breakpoint in Debugger Sidebar
6. Drag to delete the Breakpoint from the TextEditor's gutter
  => The breakpoint is deleted but the ContentView unexpectedly changes to easySlider.min.js

Notes:
- When deleting BreakpointTreeElements from the sidebar via the Delete keyboard shortcuts I would expect ContentView changes
- When deleting BreakpointTreeElements in other ways (Context Menu, Drag + Delete from gutter) I do not expect ContentView changes

Maybe we should select the parent so the resource is selected to match the visible view?

If this is the last BreakpointTreeElement then the parent (ResourceTreeElement) will be removed.

We could select the resource in the resources TreeOutline but that might be offscreen which means, should we scroll to it? No selection is actually what I felt best with.
