Bug 224274 – window.closed of opened window remains false when it is closed in standalone mode

• Status: RESOLVED
• Resolution: MOVED
• Component: DOM

Minimal repro: https://wuchenhao.github.io/open-window/index.html

Symptom: when a window is opened from standalone mode, its `closed` property is not updated to `true` when the window is closed.

Repro steps:
  1. Visit above URL on iPhone
  2. Add the page to home screen
  3. Open the page from home screen (page should be opened in standalone mode)
  4. Click the "Open Window" button. A blank page should be opened.
  5. Close the blank page. Observe that there is no alert window showing up - indicating that `window.closed` remains `false`.

Additional information:
  1. The issue only exists in iOS standalone mode. Also Mac Safari doesn't exhibit this issue.

I would expect that `window.closed` is set to `true` after the window is closed.

Thanks for filing, this worked as expected as recently as iOS 14.2.1. I can reproduce this issue on the latest iOS 14.5 beta.

Thanks! Also this issue can only be reproduced on real phones. Simulators do not have this problem.

It appears the bug in not in WebKit but in SafariViewController. The radar has been forwarded to the SafariViewController team. Closing this WebKit bug.

This should now be fixed in shipping software.
