Onlyoffice document server no copy and paste once download is locked in NC

Good day,
following issue/bug.

NC 22
Debian 11
Document Server for Onlyoffice

Firefox on Windows

  1. No copy/paste at all
  2. All right clicks (also in files) are showing the right click menu of Firefox

Firefox on Debian 11
Only 1st issue persists

Chrome
Copy/paste is working only if the download is not locked in sharing options.

Maybe somebody could at least reproduce this bug?
