Fix hiding newly added windows with live_hidden_windows

Browse Source 
When we add a window and it gets hidden as the first thing, we need
to show not just the frame window, but also the window itself.
Otherwise when the window subsequently becomes visible, it will
just be an empty frame.

Add helper functions to reduce current code duplication and avoid
adding more.
