1. Press a button marked 'Switch fonts'
fonts in three components below (a Button, a Checkbox
and a Label) must change immediately.
2. Press a button marked 'Switch background'
background of three components and canvas must change.
MacOS is an exception - AWT buttons on macOS so not
change color so on macOS only canvas, checkbox
and a label should change background.
If this is the behavior that you observe press Pass,
otherwise press Fail.
