CommandButton: on click event added manually in JS doesn't work in PF 12

Describe the bug

I put below two problems in one issue, because I think that they may be connected.

1. In CommandButton on click event added manually in JS doesn’t work. Problem doesn’t exist in PF 11. I reproduced it in PF 12.0.0-RC2.

I have code:

<script>
jQuery(document).on('click', 'button', function() {
    alert('test');
});
</script>
<h:form>
    <p:commandButton action="back" value="Back" />
</h:form>

1. What’s more - I don’t have enabled option disableOnAjax="true" nor inlineAjaxStatus="true" (added in PF 12 #8301), but when I run below code

<script>
    window.onbeforeunload = function() {
        return "Your data will be lost.";
    };
</script>
<h:form>
    <p:commandButton action="back" value="Back" />
</h:form>

My button changes from:

to

I don’t want this spinner/loading to show on my button when I don’t add any of the option from #8301.

It seems impossible due to the disabled state. Some tests:

<script>
    jQuery(document).on('click', 'button', function () {
        alert('test');
    });
</script>
<p:commandButton action="back" value="Back" disableOnAjax="false" />
<button>Test</button>
<button onclick="this.disabled=true">Test</button>
<button onclick="this.disabled=true;$(this).trigger('click')">Test</button>
<button onclick="$(this).trigger('click');this.disabled=true">Test</button>
