Intellij fails to recognize successfull authentication, despite firefox reporting success

Trying to connect to Google Cloud via the plugin in both firefox and chrome (by switching default browser in OS)

### Expected Behavior

- Authentication page in browser
- IntelliJ recognizing successful authentication

### Actual Behavior

- Authentication page in browser works ("You are now authenticated with the gcloud CLI")
- IntelliJ stuck in "Sign in via the opened browser" window


### Additional Information

- IDE type (e.g. IntelliJ, Pycharm): IntelliJ Ultimate
- IDE version: 2023.1.1
- Cloud Code version (Settings > Plugins > Cloud Code): 23.4.3-222
- Cloud SDK (Settings > Cloud Code > Cloud SDK):
- Are you allowing the plugin to manage the Cloud SDK: Yes
- Version of the Cloud SDK: 429.0.0
- Operating System: Windows 10
- Browser: Firefox 112.0.2 (64-bit) - ad-block, etc. disabled; Chrome 113.0.5672.64 (no relevant ad-block or similar limiting addins)

Please note: Firefox setting "https only mode" is not enabled (which seems to have been the solution in another [ticket](https://github.com/GoogleCloudPlatform/cloud-code-intellij/issues/3081))
