Nope, I can do that exact set of steps and trigger it.

I select two projects from the top of the sidebar, do View->Focus, Perspectives->Save Window As New Perspective, click on the perspective icon to end the edit of the perspective name (imaginatively called "Perspective 8" in this case), then put it in the toolbar by control-clicking in the toolbar and dragging in the icon. Bring up the All Items perspective (which shows the Inbox), then bring up the new perspective and the first time, I'll usually get the Inbox in the display. I'll even get the Inbox on occasion when the previous view doesn't include it, such as if I ping-pong between two similar versions of this perspective (showing different projects, but otherwise the same in construction and form). Clicking on the button again always seems to fix it. Attached images show result after first invocation, second invocation, and the perspective details.
