I am seeing an issue with opening the browser in my Ionic/Angular/Capacitor app, specifically on the Android platform. The Capacitor browser flashes open and closes immediately but fails the login.
Attempts to call the /token endpoint fail with ‘JSON Exception’ when this.auth0.handleRedirectCallback(url) is called.
Attempts to call the /token endpoint fail with ‘JSON Exception’ when this.auth0.handleRedirectCallback(url) is called.
It looks like the Auth0 SDK is trying to send the /token request with the body of a string when it is expecting a JSON:
org.json.JSONException: JSValue could not be coerced to JSObject.
The capacitor/android package had a bug regarding how it sent requests with url-encoded type header requests. It was this exact issue:

### Platform(s)
<!--
List the platforms that this bug affects.
-->
1. capacitor android only - We are using capacitor.https -> enabled true flag as part of new release 4.3.0 of capcitor.
### Current Behavior
<!--
Describe how the bug manifests. Be specific.
-->
1. We know firebase access token expires after an hour.
2. We use getIdToken(true) - forcerefresh param to true, for forceful token with extended one hour token.
3. This function is returning jsonexception error when being called.
4. FirebaseError/auth-network-failed is returned with no other information.
NOTE: getIdToken() without param after logging in, returns token perfectly. But with parameter as true it fails all the time.
### Expected Behavior
<!--
Describe what the behavior should be.
-->
1. getIdToken(true) should return new token, not the error.
### Code Reproduction
<!--
To isolate the cause of the problem, we ask you to provide a minimal sample application that demonstrates the issue.
For full instructions, see: https://github.com/ionic-team/capacitor/blob/HEAD/CONTRIBUTING.md#creating-a-code-reproduction
-->
```
const app = getApp();
const auth = getAuth(app);
const updatedUser = auth.currentUser;
updatedUser?.getIdToken(true).then(token => {
console.log(token, "Forceful"); // doesn't return this
}).catch(err => {
console.error(err)
});
```
