In wpf with vb, there is no closing of a popup opened from another popup with the Staysopen property set to true.

[Perpete]

Description

In WPF with VB, I have a main window representing a toolbar.

A button in the main window opens a popup with the StaysOpen property set to True.

From a button in the popup, I open a second popup with StaysOpen set to False.

After the first time the second popup opens, it closes correctly.

After subsequent openings, this popup no longer closes when clicked outside its designated area.

Here is the test program.
