Indeed.
sage: ex=exp(2*x)+exp(-2*x); ex
e^(2*x) + e^(-2*x)
sage: maxima(ex).factor().sage()
(e^(4*x) + 1)*e^(-2*x)
sage: bool(maxima(ex).factor().sage()==ex)
I suppose this is a Sage bug; Maxima doesn't have a problem with
its factor program.
As you know, polynomial "factoring" is a process that mathematically is
defined
in a unique factorization domain, which is broken in the example
at least 2 ways, by have a denominator, and by having exponentials
