Yes, the clipboard issue is due to the isolation between application windows 
for security reasons.  It should also stop keyloggers having a go at my 
typing.  Annoying nonetheless, I hadn't realised how much I use the middle-
click clipboard feature!  Selecting text with the mouse, then using right-
click Copy (or Ctrl+c) and right-click Paste (Ctrl+v) works, as a long winded 
alternative.

I wonder if the message preview pane problem in Kmail is also caused by the 
same wayland window isolation?  Hmm ...
