How to display the "File too big" and "File type not supported" error mess

(using Flow 13.0.0.beta2)

If i restrict the Upload component by setting the maximum file size (#setMaxFileSize(...)) and supported file types (#setAcceptedFileTypes(...)) it works correctly. However, no feedback to the user is provided. UploadI18N contains a “tooManyFiles” message. However, this message is not showing up if i upload a file, exceeding the maximum file size.

Any progress/resolution/workaround to this?
