### Steps to Reproduce

1. Open the minimal Reproduction
2. Update the values of `toolbox.emphasis.iconStyle.textPosition` and/or `toolbox.emphasis.iconStyle.textAlign`

### Current Behavior

Updating the values of `textPosition` and `textAlign` does nothing.
- `textPosition` is always at the bottom of the icon
- `textAlign` looks to be always "right"

### Expected Behavior

- Updating `toolbox.emphasis.iconStyle.textPosition` should change the position of the text relative to the icon.
- Updating `toolbox.emphasis.iconStyle.textAlign` should change the alignment of the text.

### Environment

```markdown
- OS: Linux
- Browser: Firefox
- Framework: React
```

### Any additional comments?

When I add other features (like brush), the icons on the left seem to reflect the update (the left positioning is still weird), but the icons on the right do not.
