Description of problem:
Sometime recently, while I was using Fedora 33, around March 2021, the middle mouse paste function stopped working. I upgraded to Fedora 34 yesterday (30/4/2021) and still have the problem.
None of the (mainly closed) bugs seem to be quite this problem.
Version-Release number of selected component (if applicable):
Fedora 33 and 34.
How reproducible: 100%
Steps to Reproduce:
1. Highlight text with left mouse drag.
2. Focus somewhere pastable.
3. Single click middle mouse button.
Actual results: Nothing
Expected results: Test pasted.
The component plasma-systemsettings may not be where the problem lies, but I certainly expected to find a menu option to turn on middle mouse pasting.
