Sorry if this sounds like I am "policing" you - I simply noticed your question when I was checking the questions in the close votes review queue: mathoverflow.net/review/close/119869
@ToddTrimble Could the difference be caused by different browsers? From Asaf's comments on Mathematics Meta it seems that it looks ok on Firefox and also on mobile devices.
I had this bug for quite some time. I just felt lazy reporting it. I use Chromium, but I can confirm it doesn't happen on Firefox. Might be a webkit issue. — Asaf Karagila ♦5 hours ago
Also, neither Firefox nor Chrome on Android exhibit this bug. So might also be specific to desktop. Also, I have this both in my personal computer and in my office (both Chromium, both Linux, but different versions). — Asaf Karagila ♦4 hours ago
I can confirm the bug in Chrome and in my case it is happening since today, it wasn't there before. — Sil1 min ago
