"Choose Files" button in `file_upload` example causes app to hang for linux desktop

Problem

Clicking "Choose Files" button in file_upload example causes app to hang on linux desktop ubuntu 22.04.

Steps To Reproduce

• cargo run --example file_upload
• push "Choose Files"
• app becomes stuck.

Expected behavior

Open file dialog. It hangs as if it is waiting for file selection but the file explorer is never opened. Works great on web so maybe some oddity of my OS.

Screenshots

Environment:

• Dioxus version: master@9888d36
• Rust version: 1.77.0
• OS info: XFCE Ubuntu 22.04
• App platform: desktop

• [ ] I would like to fix and I have a solution
• [ ] I don't have time to fix this right now, but maybe later

We use https://github.com/PolyMeilex/rfd to handle the file popup - can you check to see if these work for you?

Interesting, rfd cargo run --example simple worked fine.

It does not seem to make it to the handler. This does not print anything for file input:

fn app() -> Element {
    rsx! {
        input {
            r#type: "file",
            oninput: move |evt| {
                info!("file input {:?}", evt);
            }
        }
        input {
            r#type: "text",
            oninput: move |evt| {
                info!("text input {:?}", evt);
            }
        }
    }
}

Looks like this line is blocking dialog.pick_file().into_iter().collect(). Replacing it with vec![] at least prevents the app from locking up.
