Description

Describe the bug

When you reload a WebView while an asynchronous command is running, the command you initiated is automatically re-invoked.

Reproduction

https://github.com/kanatapple/tauri-app-command

  1. Run app
  2. Open Dev Tools
  3. Click greet button
  4. Execute location.reload() in Dev Tools(while the greet command is running)

Expected behavior

Unfinished commands are not re-invoked when the WebView reloads.

Research direction
Investigate the Tauri command invocation lifecycle during WebView reload. Look at the command dispatch logic in the Rust core (likely in the `tauri::command` module). Check whether commands are properly cancelled or cleaned up when the WebView navigates away. Proposed fix: ensure that any pending async commands are not automatically re invoked on reload, possibly by resetting command state or ignoring stale invocations. Review existing tests and add integration tests for reload behavior.
