Ok, here is the setup:
Element#1 action is to fadeIn element#2 (2 sec)
Element#2 action fades out itself (2 sec)
Scenario (interact mode hangs or significantly slows down):
Click Element#1 (to show element#2)
While Element#2 is being animated (faded in), click it.
First, it will not fade out, not even after it is fully shown. Second, other items in the page will not interact, or interact slowly.
