Status: RESOLVED WORKSFORME

(DevTools :: Debugger, defect)

Attachment: video - Clicking breakpoint checkbox in debugger moves click target (checkbox) from under the mouse.webm

STR:   (Win7_64, Nightly 43, 32bit, ID 20150909030223, new profile, safe mode)
1. Open   chrome://browser/content/browser.xul
2. Press Ctrl+Shift+S to open Debugger (I chose thas page to make the scripts list scrollable)
3. Scroll list of scripts (in left sidebar) to the end
4. Click the upper fully-visible script in the sidebar
5. Set 3 breakpoints in that script
6. Scroll list of scripts (in left sidebar) to the end
7. Click the last visible breakpoint checkbox

Result:   When I press left mouse button, current script block in the sidebar (title + checkboxes)
          scrolls into vide, and target element (checkbox) moves to another place, so
         'mouseup' event doesn't fire on the same element as 'mousedown'

Expectations: When I click the checkbox, it may move, but must change its state.
              I mean, it could still move on mouseup, after changing the state.

Note:     the same applies to rest of line after checkbox. Clicking the rest of line should open
          corresponding script at said line number. So, that mechanism doesn't work too.

No longer happens in new debugger.
