Description

> Please provide us with the following information:
> ---------------------------------------------------------------

### This issue is for a: (mark with an `x`)
```
- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)
```

### Minimal steps to reproduce

- Anonymous auth method, retrieve map access token from Azure Maps via App Service and System Managed Identity.
- Put tab in background.
- Wait for token to be expired ~24hrs?.
- Move map and request for tiles.

### Any log messages given by the failure

Error: "Token Expired, Try again"

### Expected/desired behavior

Should handle an expired token rather than throwing an exception.

### OS and Version?
> Windows 7, 8 or 10. Linux (which distribution). macOS (Yosemite? El Capitan? Sierra?)

- macOS 14.1
- MS Edge 118.0.2088.76

### Versions
>

### Mention any other details that might be useful
AAD might still give out a valid token (with 5 seconds left of validity) which could expire by the time the front end receives it. We cannot control or force a fresh token from AAD so expired tokens should be handled by the map library instead - auto retry or whatever rather than just throwing exception.

See problem line where it gives up:
