Summary: Clipboard managers and middle click paste are new protocols. We want to be able to copy from a clipboard manager to a regular clipboard and vice versa without duplicating loads of code. If we support kliper's "syncronise contents of the clipboard and selection" inside the compositor that would become an unmanageable amount of combinations. It also potentially allows the idea of our XWayland bridge not being a wayland client and simplifying that code. Test Plan: Unit test passes Reviewers: #kwin Subscribers: zzag Differential Revision: https://phabricator.kde.org/D29329
