Not fixed on Debian testing with Plasma 5.19.5-4 The upsteam bug report mentioned above has not resolved the issue yet: the latest comment from 2020-11-05 20:33:37 UTC still discusses a possible solution. Additionally a question for backporting was left unanswered, bug fixing concentrates on the branch Plasma/5.20. So, there is no fix even on the newest version, hence no backport to this bug's version.
