Pathname.new('/Users/username') + '/Desktop'  #=> #<Pathname:/Desktop>

I would have expected it to return #<Pathname:/Users/username/Desktop> similar to the behavior of File.join.

I see that this behavior is documented in the code examples, but it is not explicitly mentioned. It is also semantically unusual to have a '+' method discard an operand.
