Squarespace 7.1 Issue

[PeterSloan]

We are having issues with an embedded map in SquareSpace 7.1 Everything seems to work with the original map code on SquareSpace 7.0 but 7.1 fails specifically when attempting to include any reference to this file:

<script src="https://js.arcgis.com/4.13/"></script>

In fact a blank page with a reference to this file, redirected or not, will break Squarespace so that you can't save the page:

https://js.arcgis.com/4.13/

https://js.arcgis.com/4.13/dojo/dojo.js 

Also fails on latest:

<script src="https://js.arcgis.com/4.32/"></script>

Any assistance would be appreciated.
