Eframe application window does not close

[tye-exe]

Describe the bug
There is bug with eframe where the application window remains open and cannot be closed while the program is running. If the previous window is left in this state for too long, the program is reported as not responding, even though code execution that does not involve the GUI still continues.

The application window is removed when the entire program exits.
Alternatively, calling the "run_native" method replaces the previous window with a new one.

To Reproduce
Steps to reproduce the behavior:

1. Clone the repository that demonstrates the issue: https://github.com/tye-exe/egui_no_close .
2. Run the application with cargo run.
3. Attempt to close the window by clicking the "x" button.
4. The window will remain open.

(The example program must be stopped via "Ctrl+C")

Expected behavior
There should be no eframe window open after it is closed.

Video Example
See here (window is replaced via calling "run_native").

Desktop:

• OS: NixOS 24.11 (to reproduce entire system see my config)
• Browser N/A
• Version N/A

Additional context
Attempting to update to winit master branch (currently https://github.com/rust-windowing/winit/tree/cdbdd974fbf79b82b3fb1a4bc84ed717312a3bd2) did not resolve this issue.

I am currently trying to resolve this issue in eframe, but progress is slow as i'm unsure as to what i am doing.

I know that this is possible, as running the winit run on demand example shows the expected behavior.

Any additional help would be appreciated.
