[joy-ui][Input] Input element `onChange` nested in MenuItem does not fire.

Steps to reproduce

(All text is translated by DeepL.)

Here is a repository you can run right away.

Later, after reading the documentation, I tried to reproduce the code with this repository in StackBlitz, but was unable to do so because the preview showed "Error fetching cached project bundle for preview.".

It does not work in my environment, but I will share the link.

Steps:

1. Start a dev server from a project in the repository or StackBlitz (if it works).
2. Upload files from the Input element wrapped in a menu.
3. Check the Console in the developer tools.

Current behavior

When I check the Console in the developer tools, there is no output.

(Is it the intended behavior that onChange does not fire here?)

Expected behavior

The following log output is expected

menuInput ▶ FileList {0: File, length: 1}

Context

We would like to be able to access the ability to upload files from the menu, as mentioned in the example repository.

Start by running the linked BUGREPORT-Joy-upload_in_menu reproduction and compare it with the StackBlitz example if available. Trace the Joy UI Input and MenuItem entry points to determine why the file input's onChange is not observed when nested in the menu, then add a regression test showing the expected FileList output.
