The Customizer and Theme Installer open in full overlays that need to receive focus. Also, keyboard navigation should be constrained within the overlays. Using CSS `visibility` to hide all the content except the overlays, makes them the only available and focusable content and allows browsers to handle focus natively. See #29158. Fixes #33228, #27705.
