`:browser_ip` is used within Shopify, and there was probably just a mixup when this was first added. The standard way is using `:ip`, so by still assigning it to `:browser_ip`, it will not work for anyone just passing `:ip`. Since `:browser_ip` never worked in the first place, I think removing the reference to it, and slicing `:ip` as part of the accepted options to add into `post` is the way to go?
