Expandable card doesn't hide subnavbar

Hi again.

We’d like to report that, The expandable card, when expanded, doesn’t hide the subnavbar, while it correctly hides the navbar.

We managed to hide it somehow, but we don’t know if it’s the expected behaviour…

It doesn’t and it is expected, as Subnavbar is out of the hidden navbar. Just listen for card:open/close events and hide it manually with something like $('.subnavbar').hide()/.show()
