Please, check if this is an issue on sammcewan's fork (which is actively maintained), and report it there if it is. Thanks.

It occur for me too. The reason is observer adding double called after animation done but the observer removing call only once when controller do dismiss.

I just turn off animation, popover works well in this repo.
