Basically what I said.

Easy way to reproduce:

Go to a map with lots of hotspots, go to the last page. Filter by one category.

It ends up loading forever and in the console there's an error:

RangeError: `currentPage` must be firstPage <= currentPage > totalPages if 1-based. Got 3.

You'll see that it also happens on the demo, so it's not something I messed up with my overrides

Not sure what the ideal behavior is; probably the easiest fix would be to return to the first page after filtering (though only through the form...? It doesn't happen when resizing or moving around as far as I can tell).
