Datepicker: change event is triggered with `mask=true` when leaving input without changes

Describe the bug

The first time I pick any date the ajax event is called twice, this can be checked through F12 the first ajax sends an empty date, and the second the value picked.

<p:datePicker id="value"
		      value="#{testView.date}"
		      mask="true"
		      pattern="dd/MM/yyyy"
		      showIcon="true"
		      showOnFocus="false"> 
	<p:ajax event="change" update="date"/>		 
</p:datePicker>

Expected behavior

The event should be called just once with the correct value.

@jan666 here is a reproducer I patched for 12.0.0: pf-9259-patched.zip

Just look in \src\main\webapp\resources\primefaces by including those two patches JS files at the right location they override the ones found in 12.0.0 because the ones in your WAR take precedence.

Works great. Thanks!
