I thought selectstart doesn't fire for programatically set selection anyway. I don't think we currently fire selectstart when a collapsed selection is replaced by a range selection for example, and this behavior matches that of MSIE. You should definitely check MSIE's behavior though.

We don't do this elsewhere for firing selectstart so I'd rather not add such a code for this specific case. If this is a bug, then we should fix all those places where we fire selectstart at once.
