Comment:

 @Andy-Schmidt Support for validity constraints was added in [41352]. You
 can see this in:

 {{{
                 if ( form.prop( 'checkValidity' ) && !
 form[0].checkValidity() ) {
                         return;
                 }
 }}}

 When you say it appears to save, does the Save button become disabled and
 the dirty state clear? Can you leave the widgets admin screen and not get
 prompted to save? Is it just that validity reporting isn't happening?
