from what I know mobile Opera has tiny market share
it looks like a browser bug
tested only on Xiaomi Redmi 4
so currently I am not planning to work on debugging this (I created it to allow comments in unlikely case that somebody notices this issue and has an idea what went wrong or for somebody who will tell me that Opera gained noticeable market share)
