Ultimate Branding Admin Help breaks QuickEdit

On my Multisite install, it turns out that Quick Editing Pages/Posts is completely squashed-looking (tested on Chrome 47.0.2526.80 m).

Took me a little while enabling and disabling plugins but I was able to narrow it down to the Ultimate Branding Plugin's 'Admin Help Content' feature. I just spent many days making help documents only to find it broke Quick Edit for some reason- I'd still like to use this feature though.

Are you guys aware of this issue or is this special to my situation? How can we fix this?

P.S. I enabled support access.
