Can this be moved up in prio, it’s pretty painful for heavy dev tools usage…

Been using Firefox all day - it’s come on nicely since I last used it in anger I must say. Finding source files is better than Chrome I think.

@bsclifton But yeah, just reloaded Chrome, it updated to 79.0.3945.117 and the highlighting is back.
