Describe the bug
Sometimes when I close my eframe app on macOS, I receive a crash notification from macOS saying that the "app quit unexpectedly".

To Reproduce
I have created a minimal reproducible example here:
https://github.com/bash/egui-issue-2768/blob/main/src/main.rs
I'm using the latest version of eframe from the master branch.

It can be a bit finicky to observe the crash message.
Sometimes it happens a few times in a row, then it doesn't.

Some observations:

• It only seems happens when the persistence crate feature is enabled and persist_native_window returns true.
• It does not happen when I quit the app using ⌘ Q.
• It does not happen when run_and_return is disabled in the NativeOptions.

Expected behavior
No crash notification.
