Topic on Extension talk:CodeMirror

I was trying to edit a category page on yue.wp with 2017 Wikitext editor and syntax highlighting turned on and saw this... the text turned white...?

Platform: Firefox 52 on Win10

Hi Deryck! That's no good. I filed task T194068 to keep track of it. Can you reproduce it using another browser or another page? That'll be helpful. Thanks!

I'll follow up on Phab!
