When you copy some text then go to an empty region in desktop and right click and select "Paste Clipboard Contents", a popup window will appear to enter a suitable filename for the file that will contain copied data, at this stage if you try to click on any launcher or panel or system tray item or desktop item it will not work and your are blocked, so any one (especially disabled people that type text using only mouse) who use virtual clipboard from apps launcher or system tray is totally blocked at this step. The worst case is when you minimize this naming popup then it's impossible to make it reappear again because the Task Manager in the panel is not accessible (the only trick is to us Alt+Tab to recover it).
Yes, this dialog is modal so it disables its parent window while it's visible. That parent is plasma, so boom, plasma becomes disabled. We would need to give it a different parent window, I suppose.
Another window where this happens is the clipboard applet's Actions Configuration window. If you click on Add Action a modal window pops up and Plasmashell's panel, desktop and kickoff are all frozen until it is closed. Reddit post with recording: https://v.redd.it/f76bt5ecqul91

Possibly this bug is a duplicate of bug 407660
Same issue, but it will have to be fixed in a different way. I believe the fix will need to be in KIO though, so moving this there.
