Comment (by joedolson):

 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) {
     event.preventDefault();
 });
 }}}

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