The highlight that happens _while your dragging the mouse_ is actually
different than the highlight from a marked region (note that the former
exists even when you have transient-mark-mode turned off).  For some
reason the `other window behavior' of these two types of highlight is
different.

Personally, I'm not bothered by the fact that a `mouse drag highlight'
happens in all windows showing a buffer, because it only happens until I
stop dragging, and so isn't particularly annoying...
