The type for property maxMenuHeight for react-select is number, but passing the string '10rem' still works? Should the type be string | number or something else?

[JackMcBride98]

export interface Props<Option, IsMulti extends boolean, Group extends GroupBase<Option>> {
    ...
    /** Maximum height of the menu before scrolling */
    maxMenuHeight: number; 
    ...
}

Passing the value '10rem' to this creates a maximum height on the component, but causes a typescript error.

I would like to be able to use rem so that it scales with the viewport.
