[Problem Description]
When you display the Popup class or its inheritor with the StaysOpen property set to False, the class captures the mouse. Affected by this behavior, the following issues occur (the ContextMenu class is used as an example):

1. When ContextMenu is displayed, you cannot click a non-client area (e.g., the Close button) by clicking it once. When you click a button twice, it can be clicked.
2. When you click another window in the same application once with ContextMenu displayed, it does not become active. You have to click it twice to make it active.
3. When ContextMenu is displayed with no active window in a WPF application, you cannot close ContextMenu by clicking another application or the desktop. (This occurs when NotifyIcon is right-clicked.)

[Suggestion]
This mouse capture behavior should be able to be controlled by a property.

Supplement:
I think the above behaviors are different from the behavior of the standard Windows OS. Furthermore, ContextMenu seems heavy in the above behaviors. Shouldn't it be much lighter?
