[Radio] Radio's `ButtonBase` has `role="button"` when using styled-components

Steps to reproduce

Link to live example: https://codesandbox.io/p/devbox/nervous-oskar-xx7s2l

Steps:

1. Use mui together with styled-components (i.e. aliasing @mui/styled-engine with @mui/styled-engine-sc)
2. Use a <Radio /> component

Current behavior

The radio's ButtonBase has a role="button". This leads to an accessibility violation since there is a radio inside of a button.
The HTML basically looks like this:

<span 
  class="MuiButtonBase-root MuiRadio-root [...]" 
  role="button">
    <input class="sc-egkSDF jccrsl PrivateSwitchBase-input" type="radio">
    <span class="sc-fAUdSK cyWAma">
      <svg>[...]</svg>
    </span>
    <span class="MuiTouchRipple-root-hfoSaC iZusHU MuiTouchRipple-root"></span>
</span>

Note that there is a role="button" on the outermost <span>. This should not be there and is in fact not there if you use the "regular" emotion adapter for @mui/styled-engine.

Expected behavior

There is no role="button" on the ButtonBase for a <Radio />.

Context

I think the problem is that <SwitchBase /> passes role={undefined} to the <SwitchBaseRoot /> (which is a styled <ButtonBase />) here: https://github.com/mui/material-ui/blob/master/packages/mui-material/src/internal/SwitchBase.js#L177
And I guess that styled-components just swallows properties with undefined values (since version 6?).
It used to work with mui v5 and styled-components v5.

This bug also affects other components that use <SwitchBase /> (like <Checkbox /> or <Switch />).
