Issue

When the panel (at the top of the screen) is set to "Intelligently hide panel", maximizing an application window does not hide the panel. Rather, the panel remains visible and obscures the top of the application window.

Steps to reproduce

1. Set the panel to "Intelligently hide panel".
2. Open an application window (not maximized).
3. Maximize the application window.
4. Notice that the panel remains visible and is obscuring the top of the application window.

Expected behaviour

Maximizing an application window should hide the panel.
