@burnout426 Thank you!
You saved my mind. New Opera One is a new piece of shit only.

This is very annoying bug. How long does it take to fix it?

Сегодня столкнулся с этой проблемой тоже. ОС - Linux Mint. На Windows всё работает, как ни странно.

Not working in new versions of Opera (65 and above).
