Modal activation scrolls page to top automatically

The modal link I am trying to use is in the second fold of the page, but every time the modal is activated, the page in the background automatically scrolls to the top of the page. Is there a way I can stop this behavior?

I would like to see a solution to this please. I'm sure it's an easy fix!

I have worked out what is going on with this thanks to this post https://stackoverflow.com/a/54747795

I edited the js, changing
this.$body.css("overflow","hidden")
to
this.$body.css("overflow","unset")

...and it did the trick!

This issue seems fixed in the current version. See the demo

This issue is not fixed, I'm having the scroll top issue.

Changing if(this.$body=o("body") to if(this.$body=o("html") will be much better.
