Microsoft Teams Download Page (Firefox vs Chrome)

I'm suspecting this isn't expected behavior but when i am trying to download the teams client for mac on a firefox, i only get a windows installer. I am appropriately getting a mac installer when I'm on chrome however.

Is this a known bug? or is it a feature?
