So I did a test with no comments Vs having a comment. I use this comment as a SHORTCode via using a child theme. With no comments I don’t get this in google page insights:
Does not use passive listeners to improve scrolling performance
Consider marking your touch and wheel event listeners aspassive
to improve your page’s scroll performance. Learn more.
URL
Location
../wp-includes/js/comment-reply.min.jsjs/comment-reply.min.js(cdn.statically.io)
line: 1Yes I am using statically CDN.
Here is list of code from my CHild theme.
Here is my code for my comments (comments.php:

Here is code for my single post (Single.php):
https://hasteb.in/nocotovo.js
Here is my functions.php (theme functions) for which has the shortcode thing for comments:
function display_comment_list() {
ob_start();
global $post;
//print_r($meta);
?>
<?php get_comments();
comments_template();?><?php return ob_get_clean();
}
add_shortcode(‘comment-list’, ‘display_comment_list’);October 14, 2020 at 2:55 am #1488189DavidStaffCustomer SupportHi there,
this is a known WordPress ‘bug’ – it is not something that the Theme can fix. Here is one of the more recent CoreTracs raised on the issue:
https://core.trac.wordpress.org/ticket/47510
As you can see a proposed solution has yet to be implemented.
There was one fix found here:
https://stackoverflow.com/a/45974787
But please note the comments as this fix may interfere with other scripts.
January 7, 2021 at 11:13 pm #1610431CharbelThank you @David,
Could you please advise how to implement the fix noted on Stackoverflow here? https://stackoverflow.com/a/45974787
I am running GeneratePress with Dispatch Theme. I have a staging site and willing to try it.
Many Thanks!

If its about adding the script provided, you can add it in using Code Snippets plugin.
https://wordpress.org/plugins/code-snippets/Add new snippet and place this code in:
add_action( 'wp_footer', function () { ?> <script> (function() { var supportsPassive = eventListenerOptionsSupported(); if (supportsPassive) { var addEvent = EventTarget.prototype.addEventListener; overwriteAddEvent(addEvent); } function overwriteAddEvent(superMethod) { var defaultOptions = { passive: true, capture: false }; EventTarget.prototype.addEventListener = function(type, listener, options) { var usesListenerOptions = typeof options === 'object'; var useCapture = usesListenerOptions ? options.capture : options; options = usesListenerOptions ? options : {}; options.passive = options.passive !== undefined ? options.passive : defaultOptions.passive; options.capture = useCapture !== undefined ? useCapture : defaultOptions.capture; superMethod.call(this, type, listener, options); }; } function eventListenerOptionsSupported() { var supported = false; try { var opts = Object.defineProperty({}, 'passive', { get: function() { supported = true; } }); window.addEventListener("test", null, opts); } catch (e) {} return supported; } })(); </script> <?php } );
January 7, 2021 at 11:58 pm #1610466CharbelThank you @Elvin, much appreciated for your quick response.
Can I add the code above directly to my function.php Child Theme instead?

Ah sure you can do that too if you don’t want to use the plugin. π
January 8, 2021 at 12:05 am #1610472CharbelThank you so much @Elvin!!!
I used your code and paste it directly in my function.php.
Finally, the warning is gone now from Google PageSpeed Insights πYesterday, I tried the code noted on Stackoverflow https://stackoverflow.com/a/45974787, however, I got an error when Updating my function.php, it could be a Syntax error.
Many Thanks!!!
January 8, 2021 at 12:25 am #1610483ElvinStaffCustomer SupportPerhaps you forgot to place it inside a wp_footer hook.
This
add_action( 'wp_footer', ... );
line is pretty important.No problem. Glad to be of any help. π
January 8, 2021 at 1:19 am #1610528CharbelThank you @Elvin,
Yes, the
add_action( 'wp_footer', ... );
was missing from Stackoverflow example.All the best,
January 8, 2021 at 1:22 am #1610534ElvinStaffCustomer SupportNo problem. π
January 11, 2021 at 10:58 am #1614803linuxwolfHi Elvin,
Thank you so much. I have used the code directly with the code snippet by pressing the “Add new” button. It is working, although many things to improve.

Nice one. Glad you’re figuring things out. No problem. π
March 6, 2021 at 9:10 am #1684670t29k75Hi Elvin,
If I can ask directly…I used the above snippet in functions.php.
It did the job, except after adding it, Lightbox plugin stopped working.
Could something be changed within the code that it will not affect Lightbox plugin?
thanks,
Tibor

Just checked the page and lightbox gallery is working for me?
March 6, 2021 at 6:41 pm #1685019t29k75Hi Leo,
I put that snippet back to functions.php now.
Lightbox Gallery is not working, Any easy fix within the code?
thanks -
