Chris,
I have the same problem. I am using Firefox. I have cleared the browser history and cookies, rebooted, and tried both from a profile and from a free space page (my pictures).
I tried Chrome and it is working.
I didn't see anything obvious looking at the page source.
Sounds like something for the WikiTechs to take a look at. Ah, see you are also Firefox. I am on release 62.0.
