Repeated trailing slashes in base URL

When a base URL like 'https://api.github.com///' is joined with a path like '/users', the resulting URL contains an extra slash between the host and the path instead of a single separator.

Initial failing signalDouble slash between host and pathExpected behavior: Combining 'https://api.github.com///' with '/users' yields 'https://api.github.com/users', with exactly one slash separating host from path. · actual behavior: Combining 'https://api.github.com///' with '/users' yields 'https://api.github.com//users', with two slashes between the host and the path.
