Bug 110466 – Web Inspector: Remove CPU profile from a group causes exception

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

[Alexei Filippov]

To reproduce collect several CPU profiles with the same name, e.g.:
console.profile("alph");
console.profileEnd("alph");
console.profile("alph");
console.profileEnd("alph");

and try to remove these profiles one-by-one from UI. An exception is raised.

Why do we skip temporary profiles?

You don't need the suite since there is only one test.

Can you check that the group and all profiles are actually removed from the profiles panel sidebar?

I don't want'em to form groups.

I made it consistent to other tests, e.g. cpu-profiler-profiling.html
Well, removed the suite usage.

_profiles should be empty because of the loop condition. Added a check for _profileGroups.

I meant checking that there are no entries in the sidebar no in the profiles collection.
