1232299 - TypeError: cm is undefined: Editor.prototype.setOption logspam on browser_toolbox_window_title_changes.js and others

Status: RESOLVED INVALID

(DevTools :: Debugger, defect)

Description

[Brian Grinstead [:bgrins]]

STR:
./mach mochitest devtools/client/framework/test/browser_toolbox_window_title_changes.js

Test passes but I see this exception in the logs.  Which means it shows up in summaries when something else fails, like in the osx 10.10 dt2 run here: https://treeherder.mozilla.org/#/jobs?repo=try&revision=e7ed1be6e45b&selectedJob=14497211.

I'm assuming this started after Bug 1200798 because I don't see the spam in the raw log for: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=13022e404bfd&selectedJob=2802293 (the m-c push before that landed) but I do in https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=a0897ec629f9&selectedJob=2807322.  James, can you please take a look?

Yeah, I'll take a look later this week.

This test is currently enabled so I'm presuming it's working fine.
