Current Behavior 😯

Exact same issue as described HERE except it is occurring for the @material-ui/lab package.

../../../node_modules/@material-ui/lab/ToggleButton/ToggleButton.d.ts(6,18): error TS2430: Interface 'ToggleButtonProps' incorrectly extends interface 'Pick<ButtonBaseProps, "media" | "color" | "hidden" | "style" | "disabled" | "form" | "title" | "children" | "defaultChecked" | "defaultValue" | "suppressContentEditableWarning" | ... 269 more ... | "TouchRippleProps"> & StyledComponentProps<...> & { ...; }'.
