### Additional context

_No response_

Start at the Fusion Mobile DatePicker.EmbedDatePicker entry point and reproduce the issue with the supplied validRange dates, comparing the displayed range with the selection limit. Done means the component displays and permits dates only through 2004-01-01 without requiring a time-adjusted date value.
