Initial focus in a date field does not select the text nor does it have a selectAll method

If you have a DateField and focus it, the date string will not be selected. This also applies to TextInput, but for TextInput there's a selectAll method.

Could you automatically select the text for a focused date field or implement a selectAll method for DateField. If you tabulate out of a date field and tabulate back, the text wil automatically be selected, so why not for the initial focus?

import java.time.LocalDate;

import com.vaadin.server.VaadinRequest;
import com.vaadin.ui.DateField;
import com.vaadin.ui.UI;

public class ParsableDateFieldTestUI extends UI {

	@Override
	protected void init(VaadinRequest vaadinRequest) {
		DateField dateField = new DateField();
		dateField.setValue(LocalDate.now());
		dateField.focus();
		setContent(dateField);
	}
}

Start with DateField and the provided ParsableDateFieldTestUI entry point, then compare its initial focus behavior with TextInput's selectAll behavior. Confirm the expected behavior for initial focus and focus after tabbing, and consider the issue complete when the date text is selected or DateField exposes equivalent selectAll behavior.
