When I use the multiple option in a select dropdown - safari runs into weird issues. When I select an option and say Done, the dropdown goes back to showing \'0 items\'. But
This has partly been fixed in 7.1 that was released the other day, however, there are still many issues. Item count is now correct, but...
you can select optgroup titles (you should not be able to do this, and if so, it should at least select/unselect the entire group.
if you disable an option you can still select it which of course it totally wrong as well.
Get it together Apple.
