Fix async error not caught introduced by feat: supports top-level await and namespace isolation #750

Fix errors may not show up in console when injecting page context

• For example, the page script prevented the default event:

  window.addEventListener('unhandledrejection', (event) => {
      event.stopImmediatePropagation();
      event.preventDefault();
  });

Fix the sourceURL resource not show up when the script name contains quotation marks
