Accessibility acts differently depending on whether a subnode has a cornerRadius

[rcancro]

Hello,

I'm seeing inconsistent accessibility results depending on whether or not a button's subnode has a cornerRadius set or not!

I've created a sample app here with a readme file to help explain the situation.

The gist of the findings is that when I try to create a badged button, the badge gets the focus off the screen reader:

UNLESS the badge has no corner radius:

I've tried setting the cornerRadius in the most un-texturey way I can (self.button.view.layer.cornerRadius = 10), but it still causes the screen reader to focus on the badge! Making the badge layer backed is a work around, but I'd like to figure out what is really going on.

Thanks!!!
Ricky
