Thanks for the report!  I can reproduce the issue here as well.

While the regression may have appeared because of bug 1380294, it's quite likely the RDM is one that needs to make a change here.  But, more investigation is needed for a definitive answer.

I'm encountering the same issue under identical circumstances, but in Firefox 64.0

However, no message appears in the browser console. Apologies in advance for any breach of Bugzilla etiquette, in my ignorance, by appending this message to the thread.
