Unfortunately the sandbox tells me the dependencies are missing somehow, although I followed the documentation guide on how to build a reproduction case. As a consequence, the bug is not reproduced. Here is the link in case it might help:

Current behavior

The Select component's type has a placeholder prop, however this property does not exist in the Select implementation. I have checked the documentation of v4, v5, v6 and could only find examples of implementing a placeholder by hand. I have not found any placeholder prop. On top of that, adding a placeholder prop to the Select doesn't do anything.

If my understanding is correct, the problem comes from the BaseSelectProps interface, which extends a portion of InputProps. InputProps has a placeholder property. This property is not omitted in the InputProps extension of BaseSelectProps, which as a consequence means the Select has a placeholder property:

From Select/Select.d.ts, line 13:

export interface BaseSelectProps<Value = unknown>
  extends StandardProps<InputProps, 'value' | 'onChange'> {

Expected behavior

The Select component must not have a placeholder prop.

I suppose this is the right solution:

export interface BaseSelectProps<Value = unknown>
  extends StandardProps<InputProps, 'value' | 'onChange' | 'placeholder'> {
