Comment (by jdgrimes):

 > So, I assumed that I should be able to encode the entity myself, and
 then apply esc_attr() since esc_attr() advertises that it "will never
 double encode entities"
 (https://codex.wordpress.org/Function_Reference/esc_attr).

 The actual [https://developer.wordpress.org/reference/functions/esc_attr/
 inline docs of esc_attr()] make no such claim, this is just another case
 of the codex being wrong.
