Feature: pointer-events: duplicate-event; for a href anchor

[wesleyolis]

Proposal
I would like to propose that for a tag element with an anchor href specified, which doesn't cause a page to reload,
that one can cause the click pointer event on the element to not be swallowed, this would allow one to use a host of CSS tricks
in the future with anchors, were one could automatically close menu items, by having a hidden checkbox or radio box toggled in the background.

duplicate or duplicate-passthrough, the naming is not as important for now, but the concept.

The following would cause the point click event to not be followed by the element and be duplicated and propagated to non-javascript CSS elements for processing still. In which case it would cause the checkbox to be toggled on/off in the background as well.
In the bigger picture the many other little tricks I am sure we shall find for it.

a.dup {
pointer-events: duplicate;     
}
label input {
position:absolute;
opacity: 0;  
height: 0;
width: 0;   
}

#opt :checked ~ menu {
display:block
}

<label>
Show Menu
<input id='opt' type="checkbox">
<div id="menu">
<a href="#anchor1">some jump link</a>
</div>
</lable>
