Subject: [PATCH] Client: do not empty clipboard when a new popup/window is opened

If we open a new popup or a window within the same app we have to avoid
invalidating selection offer when losing focus, because it's still the
same client who has the focus and we might not get a new selection offer
by the compositor and therefore we would lose clipboard content.

Fixes: QTBUG-93474
Pick-to: 6.2 5.15
Change-Id: Ia2ef826c2967b1daf1cdeb085e8dae66d090dbcf
