Can't download based on circle

The URL below will show me observations within a given radius of a given point:

However, if I try to download from that page, the query shown is reset to just:
quality_grade=any&identifications=any&verifiable=true (

I can paste “observations?lat=43.6613779&lng=-79.338528&radius=5” in but it doesn’t register properly, and all iNat observations are still returned which I obviosuly can’t download.
