I spent a lot of time studying the Scintilla source and trying various 
things there and in splitwindow.c.  I don't see anywhere that Scintilla 
is breaking the PRIMARY selection.  It seems to become the owner of the 
PRIMARY selection in ScintillaGTK::ClaimSelection() whenever text is 
selected, but I can't figure for life of me why it it's not working.  It 
seems like it should own the PRIMARY selection in each widget where 
you're selecting text.  Even setting the owner of the primary selection 
manually to the "original" scintilla, it still locks into the "split" 

So after spending way too much time on this, and getting nowhere, I give 
up.  I'm attaching a patch that no dev is going to like because it 
behaves differently on Windows than it does on non-Windows to work 
around a know issue in GTK+ that is not documented to affect Windows 
differently than X windows.  Either someone else needs to find the root 
of the problem deep inside GTK+ (ie. why it reparenting only breaks on 
Windows), we figure out what's happening in Scintilla, we use the 
slightly hacky approach of behaving differently on Windows, or we just 
leave the whole plugin stay disable and let the Windows users not have 
it, even though we *can* make it working.  Since it's just a plugin, 
completely separate from the core code, which is already kinda hacky 
with what it's doing, my opinion is just to use the patch.

It's not my call, but the patch is here if you want it.
