html that confirms the aspect-ratio problem, and videos of other browsers

Environment
* M1 MacBook Pro 2020
  - macOS 14.1.1 (23B81)
  - Safari 17.1 (19616.2.9.11.7)
* iOS Simulator (iPhone 15 Pro Max)
  - iOS 17.0

In Safari, when `overflow` and `aspect-ratio` are set to a child element of `display: flex` and the screen is resized, the `aspect-ratio` of the child element is not maintained.
You can see the problem by opening the attached file `aspect-ratio-test.html` and resizing the screen using responsive mode.
I expect that if I specify `aspect-ratio: 1 / 1`, the element will be displayed square.
Thank you in advance.
