[bug] [dialog] core dump on window close, when using open dialog

[onlyJakob]

Steps to reproduce:

1. create a tauri app (in my case with sveltekit, but i don't think it matters)
2. use the open Dialog from @tauri-apps/plugin-dialog somewhere
3. build the app (eg npm run tauri build -- --no-bundle)
4. execute the binary (eg ./src-tauri/target/release/tauri-dialog-core-dump)
5. open and close the dialog
6. close the main window
7. Aborted (core dumped)

OS: openSUSE Tumbleweed x86_64
