I'm using the hearth situation (love it) but after it triggers, then none of my mousebutton-to-action-bar binds work. They all popup the error

"DynamicCam has been blocked from an action only available to the Blizzard UI"

steps to reproduce:

1. have a hearthstone on your action bar

2. click it and watch the camera spin and zoom as you wave your hands

3. let the hearth complete or interupt it, your choice, same result:

4. click any of your mouse buttons that you have bound to buttons (with spells/abilities) on your action bar - for example, my mouse button #5 is bound to the "-" key which is frost nova on my action bar.

5. observe the "blocked" error poppup message

The error popup doesn't happen if I directly point my mouse at the button and left-click it. It doesn't happen if the button has "summon favorite mount" instead of a spell. The problem is fixed when I reload the ui, but, comes back next time I hearth/portal/etc
