Unexpected results with http_error()

I am having some issues with unexpected results from http_error(). Documentation and examples show that the input can pass a url to the function or a response object. However, I am having issues with the url: https://egisdata.baltimorecity.gov/egis/rest/services/CityView/Liquor_Licenses/MapServer/0. If I just pass the url to http_error I get TRUE (there was an error), but if I pass a GET response for the url to http_error I get FALSE (no error; the expected result). Am I missing something or is this an issue with http_error?

library(httr)
url <- "https://egisdata.baltimorecity.gov/egis/rest/services/CityView/Liquor_Licenses/MapServer/0"
