Thanks for reporting back with and providing a test case!

This isn't a bug in jQuery. The ​offset() documentation states

jQuery does not support getting the offset coordinates of hidden elements.

which explains your problems. That it works the first time is only a "coincidence" because at that time top/left are 0. Just change .ContactPanel top/left to something different from 0px and then it also won't work on the first click.

The correct way to go about this is to use .css()

​working test case based on your code
