Comment(by mstreng):
In the case of my example above, there is a preferred embedding of L into
K, but your patch does not find it.
In general, even if there really is no preferred embedding of L into K,
then just choosing one will still lead to trouble, as you'll get non-
commuting diagrams of embeddings. Instead of just choosing an embedding, I
strongly think you must raise an error (but other people may say warning,
as David did on sage-nt). This could be discussed on the mailing list.
