[bug] open app from deep link will break accessory activation policy

[rhinoc]

Describe the bug

I am building a tray app and use set_activation_policy(tauri::ActivationPolicy::Accessory) to hide icon from dock.
Recently I am adding deep link feature to my app, and I found that open app from deep link will make dock icon show again.

I also have a tray menu item to toggle window show/hide and it works just fine. Only when accessing from deep link will cause dock icon appear.

rust:

#[tauri::command]
fn show_window(app_handle: tauri::AppHandle) {
    let window = app_handle.get_webview_window("main");
    if window.is_none() {
        return;
    }
    let w = window.unwrap();
    if !w.is_visible().expect("get is_visible error") {
        let _ = w.show();
        let _ = w.set_focus();
    }
}

js:

onOpenUrl((urls) => {
    invoke("show_window");
});

Currently, my workaround is call set_activation_policy again when open url is triggered. But it won't prevent dock icon showing but only hide it quickly after it reappears, so there still is a moment that the icon showing.

Reproduction

Expected behavior

Dock icon won't show.

not gonna lie this sounds like a macos thing 🤔 you wouldn't happen to know of another app or framework where this works fine?

[rhinoc]

@FabianLars I only know native swift app works fine, for example, cleanshot x, it is a tray app and you can use deep link to open it without dock icon appearing.
btw, I found a closed issue about window.show() conflits with set_actionvation_policy #5122, don't know if it is related.
