+## Web note:

+As seen in [WEBPLT-9816](https://jira.mercatus.com/browse/WEBPLT-9816) - event listeners are being removed by the **Slick.prototype.cleanUpRows** function on breakpoints. As such, the function has been changed to the code below as described in [this StackOverflow thread](https://stackoverflow.com/questions/38183104/how-to-prevent-slick-plugin-from-removing-event-listeners)
+
+```JavaScript
+Slick.prototype.cleanUpRows = function() {
+    var _ = this, originalSlides;
+
+    if(_.options.rows > 0) {
+        originalSlides = _.$slides.children().children().clone(true);
+        originalSlides.removeAttr('style');
+        _.$slider.get(0).innerHTML = '';
+        _.$slider.append(originalSlides);
+    }
+};
+```
