One thing you might try is to set the artist wrap class to 100% width, when I looked on the published site (where this issue did appear for me,) then the elements showed normally.
It’s incredibly odd because it seems happens on random occasions (Ie it’s not broken on every load). It frequently appears on my mobile when testing and often on my desktop. I am using Chrome and this bug is being experienced by the rest of our team on separate computers/devices.
