Error in Chrome

[jrizza]

Hello,
Could you please help me with the following error when clicking in any category?:

Exception caught during observer callback: TypeError: Illegal invocation

This is happening in Chrome (Version 43.0.2357.81 (64-bit)) and not in Safari (Version 8.0.6 (10600.6.3))

I'm getting the same error on Chrome 43 both desktop and mobile. It's basically broken my app!

Working just fine in Safari too.

I've the same issue with Version 46.0.2490.86 (64-bit).

Categories on which the user is clicking are disappearing when we are going back to the full list of categories. Pretty annoying bug :/
