Able to add more than one file when maxFiles is 1 and multiple is false in PromptInput

[captchadex]

I am able to add more than one file when maxFiles is set to 1 in PromptInput and multiple is set to false.

Example:

    <PromptInput
      onSubmit={handleSubmit}
      accept={PDF_MIME_TYPE}
      multiple={false}
      maxFiles={1}
      onError={(error) => toast(error.message)}
