Remarks

The current implementation of a System.Windows.Controls.Primitives.Popup is to close itself during the PreviewMouseDown tunnel event and release capture. However, it does not mark the PreviewMouseDown as handled and so the element on which you clicked will still receive a MouseDown event. In certain cases, it is preferrable to have the mouse down that caused the click to be intercepted and not affect the element on which it was clicked until the subsequent mouse click. Setting this property to true will ensure that if the Popup's PreviewMouseDown is invoked and not handled even though the Popup was closed that the PreviewMouseDown is handled and therefore the element on which the mouse was clicked will not receive the MouseDown.

Note: This property will not affect a popup type implementation whereby the popup was closed during the PreviewMouseDownOutsideCapturedElement.
