[BUG] Display bug of the number of viewers of a stream
This is a nits and not urgent bug.
I found that the display of the number of viewers in the web UI is NaN when I locate my mouse cursor on the following streamer's icon on the left side of the page. This only happens when I use a display which has narrow width. (ex. In my case, I turn my display 90 degree and make it vertical, and I get this bug.) Please take a look and fix.
