New Post: Strange autohide un-hiding behavior on document close

Hi, Thanks for your sample.

Currently, when the active item is removed, we try to find another item to become the "active" one. If there are no more items, the first one found (from layout sides) will be set as active, thus showing the AutoHide panel.
