I would like to report another bug, now with the pinning of "Unnamed" objects.

• When nothing is selected and you Ctrl+Left click on the "Unnamed" right side in the objects list, there's no pin icon, but nothing can be selected afterwards, both in the objects list, as well as in the viewport. Only hiding and un-hiding the "Unnamed" object fixes things back to normal.
• When "Unnamed" object is selected, and you perform Ctrl+Left click on the yellow icon in the objects list, pin icon also does not occur, but now the "Unnamed" object cannot be deselected. Again only hiding and un-hiding fixes things back to normal.
