Accordion is-open doesn't work with angular.js 1.3.0

[dmatta]

I set up two examples in plunker with exactly the same accordion example except this one is using angular.js 1.2.16

And the second one is using angular.js 1.3.0

Clicking on the link under Static Header, initially expanded for 1.2.16 shows and opens the Dynamic Body Content accordion group.

Clicking on the same link for 1.3.0 shows the Dynamic Body Content accordion group but doesn't open it.

Then you have to click twice on the dynamic body content header to open the accordion group.

Please let me know if you need any more information.

Thanks!

FYI: Still seeing this in angular 1.3.8 and ui-bootstrap 0.12.0.

Yo!

I can confirm this as well (cleaned example).

I will fix that ASAP.
