I couldn't reproduce this. Have you tried disabling all browser extensions and clearing the cache?

Mototroller

@artch It suddenly disappeared several hours later. Possibly it could be an issue with local internet provider routing, and some resources and utility hosts became unreachable. Cannot reproduce it same way.

I'll try to investigate and dump it more carefully next time if it'll happen again, for now ticket is useless and can be deleted I think, thanks for response anyway.
