Incorrect type definitions for Select interface

Expected Behavior

The latest version should be consumable from a TS project. The property definitions for the Select component should be correct:

...
disabledKey?: string | ((...args: any[]) => any);
...

Actual Behavior

When using grommet components TypeScript throws an error:

/node_modules/grommet/components/Select/index.d.ts
Type error: Type expected.  TS1110

     9 |   closeOnChange?: boolean;
    10 |   disabled?: boolean | number | string | object[];
  > 11 |   disabledKey?: string | (...args: any[]) => any;
       |                           ^
