Steps to reproduce 🕹

Link to live example:

Steps:

1. Go to the Mui chip link https://mui.com/material-ui/react-chip/
2. Goto the clickable section
3. update the example with the following code
   <Chip label="Clickable" disabled skipFocusWhenDisabled={false} onClick={handleClick} /> <Chip label="Clickable" variant="outlined" onClick={handleClick} />

Current behavior 😯

If you inspect the first chip component that is disabled if you set skipFocusWhenDisabled={true} the tabIndex is set to -1 which I think is correct if you then set skipFocusWhenDisabled={false} the tabIndex is still -1 which I think is incorrect.

Expected behavior 🤔

When disabled is set to true and skipFocusWhenDisabled={false} the Index should not be -1 it should allow it to have focus.

  Don't forget to mention which browser you used.
  Output from `npx @mui/envinfo` goes here.

Start with the clickable Chip example at https://mui.com/material-ui/react-chip/ and reproduce the behavior using the two Chip snippets in the issue. Trace how disabled and skipFocusWhenDisabled determine tabIndex, then add or update coverage for both prop values; done means the observed tabIndex and focus behavior match the documented expectation.
