[Slider] Missing name property?

• This is not a v0.x issue.
• This is a Labs issue.
• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

As with other grouped form controls (e.g. RadioGroup as in the example), a library like Formik should be able to manage the form control state.

Current Behavior

Formik throws an error stating that it could not update the form control value because there was no name provided:

Warning: Formik called `handleChange`, but you forgot to pass an `id` or `name` attribute to your input:

    <span class="MuiToggleButton-label-1289">2</span>

    Formik cannot determine which value to update. For more info see https://github.com/jaredpalmer/formik#handlechange-e-reactchangeeventany--void

Steps to Reproduce

1. Create a ToggleButtonGroup or Slider with state managed via Formik
2. Attempt to select one of the options

@valeedmalik There is no fix coming, it has to be handled userland.
