Hi Brandon,

I tested this on Fedora 23 with FF 60.0.2, Build ID 20180605171542, User Agent Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0) and I can't reproduce the issue.

Hi Gyula, 

The issue exists solely within the Cinnamon environment so I believe that to be the source of the issue. I've tested this in other desktop environments and it did not occur. That being said, the issue seems to have been resolved as it does not occur anymore in the latest version of Cinnamon.

I reported this issue on their repo as well and they had found the root of Cinnamon's side.

Next question, how do I close this bug?
