Dead spot on Explore and Taxon page maps

interesting… there appears to be a dead spot in the top-left part of my Explore map (a rectangle maybe 250px tall and 500px wide, starting from the top-left corner), but only when you’re zoomed in enough that the map shows pins and not circles. if you shift some pins into that dead spot, they become unclickable. if you shift them out of the spot, they become clickable again. seems to happen in both Edge and Chrome. can anyone else confirm?
