OK, I'm seeing this too and as far as I can tell it's a bug. The button 
is supposed to grab the mouse cursor when the button goes down, and 
then send the SEL_LEFTBUTTONPRESS message to the target (and this is 
happening). But when the button goes up, it's supposed to ungrab and 
then send you SEL_LEFTBUTTONRELEASE (and this is *not* happening).

I'll try to figure out what's wrong and get this fixed ASAP.
