Twenty Twenty One: focus position jumps when opening popup

Description (last modified by joedolson)

The following was noticed in this My Calendar Github issue:

Twenty Twenty One contains code that intercepts all anchor links containing a '#' and moves scroll position to that link. This causes an undesirable focus position movement for any link containing a '#' character that is not intended to move focus.

		 * Close menu and scroll to anchor when an anchor link is clicked.
		 * Adapted from Twenty Twenty.
		 * @since Twenty Twenty-One 1.1
		document.addEventListener( 'click', function( event ) {
			// If target onclick is <a> with # within the href attribute
			if ( && '#' ) ) {
				wrapper.classList.remove( id + '-navigation-open', 'lock-scrolling' );
				twentytwentyoneToggleAriaExpanded( mobileButton );
				// Wait 550 and scroll to the anchor.
				setTimeout(function () {
					var anchor = document.getElementById(;
				}, 550);
		} );

This code adds a listener to all links that scrolls to that target anchor. For any case where a link is used to open a modal, an accordion, or as a faux-button in any way while containing a hash character, this will cause problems.

I don't think so, although it's related.

Reproduction steps:

  • Activate TwentyTwentyOne
  • Set up a primary menu. (This code is in primary-navigation.js, which is only enqueued with a menu.)
  • Create a link with an anchor, e.g. <a id="test-target" href="#target">Target</a> and a corresponding target, e.g. <div id="target"></div>
  • Add scripting to prevent the default event on the target, e.g.
var testTarget = document.getElementById( 'test-target' );
testTarget.addEventListener( 'click', function(event) {

Observe that although the event is attached, the page still scrolls to the target.

Does it still happen with PR #2833 applied?
