Thanks for the report André. I've tested this on plasmashell 5.20.2 and I can't reproduce this issue. Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I'm setting status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.
Cannot reproduce; problem no longer present.
