Controlgroup: Incorrect corner classes if hidden during initialization

[chatis]

Hello,

I use controlgroup in collapsible accordion... The first opened accordion work well and the corner are runded for controlgroup..

But when I open an other one, controlgroup aren't collapsible anymore..

I have creat a test here : ​https://jsfiddle.net/scfmwakk/

You can check that this is not working well

Thanl you

This happens when the controlgroup is hidden during initialization. For now, you can initialize the accordion after initializing the controlgroup: ​https://jsfiddle.net/scfmwakk/2/

Actually, this logic is intentional. By default, the controlgroup will only look at visible controls to determine which classes to apply. Since the controls are hidden, the controlgroup doesn't include any of them during the class determination. See the ​onlyVisible option for more details.
