Currently event-start and event-end that use mouse-set-point and posn-set-point
create an invalid event when some code inadvertently switches the buffer.

So the conclusion is following? There is a bug in the low-level
function, but we ask users to be careful and to take precautions
against stumbling on this bug. Then the problem is that such warning
should be documented somewhere.
