String issue - ("edited a while"), missing "ago"

I just edited a post and moments after saving it looked like this: a_while

As a matter of fact I edited really fast so it didn't take me "a while" (promise!), so I assume it simply wanted to say "edited a while ago" although "edited moments ago" might be more suitable.

P.S. This was on gitlab.com
