Steps to Reproduce

    <zscript><![CDATA[
    import java.time.*;
    LocalDate today = LocalDate.now();
    ]]></zscript>
    <datebox valueInLocalDate="${today}" readonly="true"/>

1. Click the calendar icon to change the date

Current Result

the date changed

Expected Result

since it's read-only, the component should not allow users to change the date

Debug Information

• multiple input components with extra buttons/icons have the same problem including: Spinner, Combobox, Timepicker...
  We should do a full checking.
