Firestore emulator UI - loading collection state does not complete when emulator is run in container

**Describe the bug**
The Firestore emulator UI is in perpetual "Loading Collection" state. This is from initial pristine state (i.e. this occurs on emulator start - no additional action needed.). I am running the emulator in a Docker container and have forwarded all the ports used by emulated features (firestore - 8080, ui - 4000, and 4500 and 4400 for good measure)

**To Reproduce**
Steps to reproduce the behavior:

1. Setup a docker container using debian image
2. Install firebase
3. Initialize the project and emulator features
4. Modify the firebase.json to add host property i.e. host: '0.0.0.0'
5. Run emulator: firebase --project emulators:start
6. Goto http://0.0.0.0/4000

**Expected behavior**
Expect to see Firestore emulated UI show no collections, and provide UI widgets to create collection and documents. Instead the 'Loading Collection' spinner is shown and it does not complete.

**Screenshots**
See

**Desktop (please complete the following information):**

- OS: MacOS, Docker (debian image)
- Browser chrome
- Version 108.0.5359.124 (Official Build) (x86_64)

**Additional context**

Thanks in advance. I want to transition the project to local emulated development workflow and being able to access the Firestore UI locally is key.
