How to avoid changing cursorShape when focus terminal window if I set `unfocusedAppearance`

Nobody has claimed this yet.

### Windows Terminal version

1.21.2911.0

### Windows build number

10.0.22631.0

### Other Software

NVIM v0.10.2

### Steps to reproduce

1. snippet in settings.json
```json
"opacity": 50,
"cursorShape": "underscore",
"unfocusedAppearance": {
"opacity": 90
},
```
2. open `nvim`, current cursor shape is `block`
3. press `alt`+`tab` to focus another window, then press it again to focus back to terminal
4. cursor shape changes to `underscore`. (If I delete the `unfocusedAppearance` in settings.json, the cursor shape does not change after focus back)

### Expected Behavior

When I set `unfocusedAppearance`, do not change my cursor shape after focus back to terminal window.

### Actual Behavior

Cursor shape changes to `underscore` that I set in `cursorShape`.

Start with the settings.json behavior for unfocusedAppearance and cursorShape, then reproduce the Alt+Tab sequence with Windows Terminal and NVIM v0.10.2 on the reported Windows build. Done means returning focus to the terminal no longer changes the configured cursor shape when only unfocusedAppearance opacity is set.
