[Problem/Bug]: Navigate to a normal web page but trigger a file download callback

What happened?

This problem occurs occasionally. Our client frequently loads a normal web page link, but sometimes it fails to load the web page and returns the error code: COREWEBVIEW2_WEB_ERROR_STATUS_CONNECTION_ABORTED

After careful analysis of the log, we found that loading this normal web page eventually triggered file download, and the API call sequence is as follows:

  Navigate(url)
  OnNavigationStarting(url)
  OnWebResourceRequested(url)
  OnNavigationCompleted(url)  //get error code  **COREWEBVIEW2_WEB_ERROR_STATUS_CONNECTION_ABORTED**
  OnDownloadStarting(url)   //Triggered to start downloading

Importance

Done means identifying why a normal page triggers the download callback and documenting a reliable reproduction and expected behavior.
