Have better support for maximized window.

Currently, if we maximize the window, our windowPosition{X,Y} become 0.
When reopening the app, we have a window with the same size of a
maximized, but without this property toggled on. This is not intuitive
for users, since it is expected to have the last non-maximized size
to be restored.
