Should i update now?
You'll have to wait until your distro updates to 20.12 - there's no way to back port to 20.04 or 20.08 unless your distro does it by manually patching it..
Distros usually backport fixes such as this. (And I see one of the Fedora maintainers is already in the CC of this report ;)). (I'll also post to distributions@kde.org to notify distro maintainers of this).
(Note you'll also need this commit https://invent.kde.org/utilities/konsole/-/commit/b193b8b1242d1570361d2388c475b5a619c19afe).
