Allow select2 fields to render HTML again

I had the same need for rendering HTML in select2 fields as in the support forum (https://support.advancedcustomfields.com/forums/topic/allow-select2-fields-to-render-html-again/). After debugging, I came to this solution:

add_action( 'acf/input/admin_footer', function() {
?>
<script>
acf.add_filter('select2_args', function( args ){
  args.templateSelection = function (selection) {
    var $selection = jQuery('<span class="acf-selection"></span>');
    // use acf.escHtml(selection.text) instead of acf.strEscape(selection.text))
    $selection.html(acf.escHtml(selection.text));
    $selection.data('element', selection.element);
    return $selection;
  }
  return args;
});
</script>
<?php
});

Maybe the ACF team would implement a filter to control the use of acf.escHtml() over acf.strEscape()? That would be really nice and would be more futureproof than overwriting it like this.

Thanks and kind regards
