Describe the bug

A metro window that opens another metro window modelessly using .Show() stays top most when the modeless window is minimised.

Steps to reproduce

See attached project. Run without attaching to debugger (when debugged is attached, the bug does not occur) Open popup window, minimise popup window. Bring other process window, e.g. win explorer to foreground. debug project main window remains in front.

Main window should not remain topmost foreground window just because a modeless popup is minimised.
