Comment (by vdelecroix):
I do not think this is a bug.
The (respective to the embedding) comparison code is used only if there is
a coercion embedding for which the codomain allows to have arbitrary
precision real intervals (right now, only `AA`/`QQbar` but could be extend
to `RLF`/`CLF`). I do not mean that it is not feasible to find the
corresponding exact embedding from a one into `RIF` one. But I would be
against using it.
What is the problem with the behavior in the ticket description?
