Current Behavior

For repro I used npm init @capacitor/app@latest and then replaced index.html body with

<button>Open browser</button>
<pre></pre>

and capacitor-welcome.js with

import { Browser } from '@capacitor/browser';

Browser.addListener('browserFinished', async () => {
  document.querySelector('pre').innerText += 'browserFinished\n';
});

document.querySelector('button').addEventListener('click', () => {
  Browser.open({
    url: 'https://example.com',
  });
});

Steps:

1. Click "open browser"
2. Minimize the browser
3. browserFinished has fired
4. It won't fire again when maximizing/minimizing or closing the browser

Expected Behavior

I expect browserFinished to tell me when the browser was closed

I open Auth0 in a browser (because of ionic-team/capacitor#7367). But I can't reliably know when the browser is done to remove the "loading" state (spinner) in my app.
