React-admin: LoadingIndicator does not get class overrides

[danejorgensen]

What you were expecting:
Can apply custom theme to LoadingIndicator component

What happened instead:
LoadingIndicator is default color. Does not pass styles to RefreshIconButton

It does pass the styles to the CircularProgress component while isLoading is true.

Steps to reproduce:

import { LoadingIndicator } from 'react-admin';

theme => ({
  indicator: {
    color: '#F00'
  }
})

<LoadingIndicator className={classes.indicator} />

Environment

• React-admin version: 3.8.4
• Last version that did not exhibit the issue (if applicable):
• React version:
• Browser:
• Stack trace (in case of a JS error):

Thanks for reporting. Indeed only the CircularProgress is passed a className.

This feature will be part of the next release. You'll have to overide the classes passed to the LoadingIndicator using the key loadedIcon.
