Bug 59476 – Web Inspector: breakpoints set in original and formatted scripts are messed up after navigation.

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Pavel Podivilov]

Web Inspector: breakpoints set in original and formatted scripts are messed up after navigation.

Also, sometimes breakpoints disappear from DebuggerPresentationModel (removed from _breakpointsWithoutSourceFile and never added to sourceFile.breakpoints).

Why did you make this call synchronous?

Is this change related?

Right after the call to WebInspector.debuggerModel.removeBreakpoint breakpoint is left in inconsistent state - it still have debuggerId. After dpm.reset breakpoint will be in that state forever. 
From the other side, since the order of calls is preserved, the calls are effectively synchronous, and it is safe to ignore the callback here.

It's a drive-by fix for minor problem with source frames that are loaded too late (after reset when there are no source files).
