ability to disable copypaste with middleclick or clear paste buffer

### Feature Idea

as a blender user im extremely used to using middle mouse to pan around the node workflow, but if i had copied something it pasted every time i pan, its very annoying. if there was a way to remove that from the keybinding settings that would be awesome, ir if you cant do that, have a method to clear the copy/paste buffer so you since it retains the buffer even after restart.

@sinesc:

I was convinced this must be a bug until I found this issue. Is there any work around at all?

@SiegeKeebsOffical:

Are you using linux KDE? It seems to be related to that from what I've seen, but would like to corroborate 

@christian-byrne:

Doesn't happen to me on gnome

@sinesc:

Happens to me on Linux Mint Cinnamon desktop with Firefox. I just realized it doesn't seem to happen in Chrome.
