When I select a region by dragging Mouse-1 starting at the "selected."
above, as soon as the mouse cursor leaves the emacs frame, the region
won't grow or shrink anymore until I enter the frame and window again.
And when I release the drag outside of the frame and window where I
started, the final region is the last one before leaving the
frame/window.  That's pretty much what I'd expect except that releasing
the drag outside of the start frame/window inactivates the region.
