Cocoa: Explicitly hide popup windows when the application is hidden
When the application is hidden then Qt will hide the popup
windows associated with it when it has lost the activation
for the application. However, when it gets to this point it
believes the popup windows to be hidden already due to the
fact that the application itself is hidden. As a result,
when the application is restored it causes a problem with
the still visible popup window as it is taking the input
events without responding to them.
Therefore we need to explicitly hide the windows right before the
application is hidden to ensure that they are actually hidden
correctly.
