Bug 199033 – Web Inspector: Debugger: setting a breakpoint on a non-JavaScript line should immediately show as unresolved

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

# STEPS TO REPRODUCE:
1. inspect any page
2. set a breakpoint on a non-<script> line of any HTML file
 => breakpoint icon shows blue
3. move (drag) the breakpoint to a different non-script line in the same file
 => breakpoint icon changes to dark grey

r=me, nice change.

Any idea why it existed in the first place?

Maybe "This parameter was only used when setting a breakpoint via...". I had to check the code to clarify.

Interesting. It looks like a breakpoint only begins its life in the resolved state when restoring breakpoints in DebuggerManager.prototype.initializeTarget (specificTarget will be non-null).

It was added in r171784.  My guess is that at the time, `breakpoint.resolved` was used as a "gate" for invoking certain backend commands, so automatically marking it as resolved would help avoid those.  Nowadays, it's not used for basically anything other than UI.
