Dear @simonnelli
The linked images have no cursor applied with CSS:

We can see the + in a screenshot which gives away that it's not the true cursor but some element on the website.
I think it may be a Unicode applied to the screen with some JS.

When i change the site's font size the Line height of + symbol increases and pushes away from where the true cursor is:

For this reason i think it's created out of Text / Unicode.
