Swing never grabs the pointer for a popup, so a click on the desktop or
another application is not seen and the menu stays up. The little window
the menu hangs off is focusable now and closes it when the focus goes
elsewhere, Escape closes it, and clicking the icon again toggles it.
Raising the window was ignored for the same reason it usually is: a
window manager refuses a raise from an application that does not have the
focus. The icon asks for _NET_ACTIVE_WINDOW instead — the request meant
for pagers and trays acting for the user — and falls back to Swing's
always-on-top shuffle when it cannot find the window. Windows are matched
by _NET_WM_PID and _NET_WM_NAME, since WM_NAME cannot carry the em dash
in our title.
