primefaces: InputMask: onchange broken with PF12

Describe the bug

inputMask in PF12 started to generate onchange events even if the value does not change. All that is enough is to click the component (focus gained) and click somewhere else (focus lost). This kills logic in my application which relies on reliably getting information if anything actually changes (inputMask used as filter with onchange script causing PF(‘dataTable’).filter()).

12.0.3:

11.0.9:

    <h:body>
        <p:log id="log" />
        <h:form id="frmTest" prependId="false">
            <p:inputMask id="testMask" widgetVar="testMask" value="#{testView.value}" mask="9999[ 9999]" onchange="PrimeFaces.info(jQuery('#testMask').val())"/>

        </h:form>
    </h:body>
