Broken when using JS aggregation

Problem/Motivation

With JS aggregation enabled (at /admin/config/development/performance), we get the following error when clicking the "Tour" button:

DOMException: IntersectionObserver constructor: rootMargin must be specified in pixels or percent.

and the tour does NOT appear.

With JS aggregation enabled, everything works fine and as expected.

The "rootMargin" code can be found in tour.js:

...
y=Le(a),_={rootMargin:-h+"px "+-m+"px "+-w+"px "+-y+"px"
 ...

Steps to reproduce

1. Define a tour for the frontend and enable aggregation.
2. See console for the error
