Calling Drupal.attachBehaviors(); Causes duplicate script tag includes [#3177430]

Problem/Motivation

Calling Drupal.attachBehaviors(); causes duplicate script lazysizes library tag includes.

Every time it is called, I end up with duplicated script tags for the main library and any plugins. In my case:

<script src="/libraries/lazysizes/lazysizes.min.js" async=""></script>
<script src="/libraries/lazysizes/plugins/unveilhooks/ls.unveilhooks.min.js" async=""></script>
<script src="/libraries/lazysizes/plugins/parent-fit/ls.parent-fit.min.js" async=""></script>
<script src="/libraries/lazysizes/plugins/object-fit/ls.object-fit.min.js" async=""></script>
<script src="/libraries/lazysizes/plugins/aspectratio/ls.aspectratio.min.js" async="">
