Issue/MR list tabs - Icons sometimes display as ?
Summary
The icons in the Issue List and MR List tabs sometimes display as (?) instead of displaying the number. I've seen this more frequently over the past couple of weeks. I can't be certain, but it seems like it might happen more frequently when toggling between tabs.
The last time this happened, I tried to toggle between tabs (to see if that would resolve it), and the entire page froze for 10+ seconds before refreshing on its own.
Refreshing does seem to resolve the problem.
