I am trying to use one accordion for two columns layout and this is only working in bootstrap 4 alpha and is NOT working since any beta release (tried even with the latest beta 3).

Steps to reproduce with CodePen examples

Take a look at this codepen - once you click on any collapsible element it stays collapsed forever unless you click on it again. However the expected behaviour is that only one element should be collapsed at a time.

Take a look at the very same HTML markup using Bootstrap Alpha 6. Everything is working as expected. You are not able to have more than a one element collapsed.
