I can't reproduce this is nightly. What version of Firefox do you see this in?

I have tested this issue on latest Firefox (51.0.1) release and latest Nightly (54.0a1) build, but I haven't managed to reproduce the issue. I have also tested this with the reported Nightly version (49.0a1), but the issue is not reproducible.

Considering this and the fact that the reporter's account is disabled, I will close this issue as Resolved - WFM. 
If anyone can reproduce this issue on latest versions, feel free to reopen the issue and provide more information.
