Let me mostly rephrase what Nils said above with a bit more of specific information. I would say this issue comes from a "feature" of ClonableArray. The default hashing of ClonableArray is to also hash in the parent and have elements in different parents not (by default) compare equal. A coercion needs to get involved for "natural" equality (i.e., ignoring the parent), which is a general issue within Sage.
