   if target and source are in the same container then the answer is 
yes, but i don't think there is any problem with it.
At least there is no visible side-effect and the corresponding 
regression tests and JCK tests are not affected by this change.
If they are in different containers then no event will be delivered to 
target until we actually drag there but it is
Ok because the enterEvent will be generated on the native layer and 
there will be no need in artificially synthesizing it.

With best regards,
