A seemingly unrelated change to cursors broke xwayland's clipboard syncing, presumably because of a change in how startup is ordered with regards to syncing between our internal wayland connection causing a crash. It was fixed with a flush, but ultimately guarding things coming up in the natural order works better. Long term plans are to finish removing the internal connection. See xwayland_selections_test in autotests.
