[Tooltip] className not applied from PopperProps

[Volcomix]

After migrating to MUI v5.0.3, our styles are not applied anymore when using PopperProps from the Tooltip component.

I saw that a new prop componentsProps was introduced in #28692. Our styles seem working fine when using this prop but TypeScript is now asking for all the popper props to be defined.

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Either className is not applied when using PopperProps or either TypeScript is yelling when assigning only the className to componentsProps.popper.

Type '{ className: string; }' is not assignable to type 'PopperProps & TooltipComponentsPropsOverrides'.
  Property 'open' is missing in type '{ className: string; }' but required in type 'PopperProps'.ts(2322)

Expected Behavior 🤔

Either className should be allowed to be passed to PopperProps or either TypeScript should allow to assign a partial PopperProps to componentsProps.popper.

Thanks for the report. Really appreciate the flawless issue.

We end up overwriting PopperProps.className in https://github.com/mui-org/material-ui/blob/f98d52b1fcf9ab91b3e8d760bf59906c860fca49/packages/mui-material/src/Tooltip/Tooltip.js#L681-L682
