Not sure whether there's a better place to report issues, but the scroll tool hasn't worked in Safari (OS X 10.15.5) for the last couple of versions for me. Holding space does give the grabbing-hand pointer and removes the cross-hatching, but click-dragging does not scroll the map.

Works fine in Firefox.

Thanks for the heads up, but Safari isn't really a browser I'm focussed on supporting because of time constraints - there's probably a lot of subtle stuff that doesn't work well in Safari
