When selecting the input field that breaks the badges, I get tons of `JavaScript error: resource://devtools/server/actors/highlighters/flexbox.js, line 311: TypeError: flex is null; can't access its "crossAxisDirection" property` in my terminal

This error can be triggered simply by flicking the flex badge on Google's input box... taking a quick look as IMO this is embarrassing.

I reproduced this issue using 65.0a1(2018-11-16), on Windows 10 x64.
I can confirm this issue is fixed, I verified using Fx 65.0b10 on Windows 10 x64, macOS 10.13 and Ubuntu 16.04 LTS.
Cheers!
