shepherd: Content is blocked by "hidden" steps

When a tour is hidden because the target is not visible on the page (e.g. because of a media query), it is blocking/masking the content behind it. This is because it’s still rendered (always in the top-left corner of the document) with just opacity: 0;.

Is this a known problem?

Possible fix

.shepherd-element[data-popper-reference-hidden]:not(.shepherd-centered) {
  opacity: 0;
  pointer-events: none; /* <- added */
}
