Update. So I've updated to 1.18.1. The bug persisted. But simply renaming the /css/redactor.css file to .bak causes the browser to stop looking for the file and osTicket goes back to normal behavior for me. Using a fresh copy of redactor.css from the 1.18.1 download sends the browser back into the forever pending load loop.
I'm going to load up a fresh copy of 1.18.1 on a new server and see if I can reproduce this.
I'm guessing redactor.css is used for text entry of some kind? What am I breaking by disabling it?
