This test expects that a single call to window.restore() will bring the window to the "normal" state. This is unfortunately not guaranteed since a window that is zoomed then minimized will restore to the zoomed state. This could cause the test to fail if window is zoomed at the start of the test, because it will return to that zoomed state mid-test. This change defines a general function to ensure that the window is in the normal state before proceeding, then calls that at the beginning of the test and in the middle of the test to ensure we are exercising the transitions we intended to exercise.

// This test checks whether fullscreen windows can transition to minimized windows,

|
|
// example, in macOS, the minimize button is greyed-out in the title bar of
|
|
// fullscreen windows, making this transition impossible for users to initiate.
|
|
// Still, web APIs do allow arbitrary combinations of window calls, and this test
|
|
// exercises some of those combinations.
