JS warning: contextual.js Adding non-passive event listener to a scroll-blocking 'touchstart' event

Open on Drupal.org →
Created on 15 September 2023, 9 months ago

Problem/Motivation

Seeing this warning in JS console:

Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952

With stack trace: 

add             @ /core/assets/vendor/jquery/jquery.min.js?v=3.7.0:2

    It is entirely possible this is coming from one or more contrib modules, however two points:

    1. The stack trace doesn't mention anything outside of core JS assets, so I don't know where/how to start troubleshooting this.
    2. There are 50 instances of this warning message in the console log, not just one.
