Pet button issues since update #440

On my warlock (haven't tested other toons yet), some of the pet bar buttons don't give hover text and are unclickable in the main button area but work properly right at the bottom of the button. Some buttons work fine, some don't. I'll follow up with more details later but wanted to get this in early. Other bars seem to be fine, I've only seen this with the pet bar. It affects multiple pets.
