(DevTools :: Style Editor, defect)

Description

[Mike Taylor [:miketaylr]]

Terrible title, plz fix.

STR)

1) Open about:home
2) Open Devtools > Style Editor
3) Click back and forth between the two styles

Expected:
Nothing fancy, just show me the styles for each stylesheet

Actual:
When you click back to the first one you showed, you get a cool split view that keeps growing... see attached gif.

I'm not seeing this in an fx-team build on OSX or a nightly on Windows.  Do you see any errors in the Browser Console when this happens?

[Mike Taylor [:miketaylr]]

Oh right, forgot about the browser console.

Each hop between stylesheets gets me a new `TypeError: cm.getInputField(...).controllers is undefined`

(I'm running the OSX 46.0a1 (2016-01-15) Nightly build, fwiw.)

That's a new one to me.  Just curious:

1) Do you hit the error with a clean profile?
2) Do you hit the error on any web-facing pages or just about:home

1) Nope, doesn't reproduce with a clean profile. Maybe close as WFM?
2) Yeah, all pages web or about: pages.

Going to close as WFM but please reopen if you see it again or figure out what profile change causes this issue.
