Web Compatibility Support • peoplescollection.wales: Item image can't be seen and text is squeezed too much to the left

I can't see the image for the item in https://www.peoplescollection.wales/items/9729, and the description is difficult to read since it's pushed to the left side of the viewport too much with excessive margins. Tested in a fresh portable of 34.1.0.

Probably relevant output from the devtools web console (link to the common JavaScript file referenced here: https://www.peoplescollection.wales/sit ... YyfvdsrdeQ):
