Hmm, it looks like the same `domain: complex` slowness issue as in #13973
is going to hit us again. Trying this in Maxima 5.33.0 with the patch
applied, the computation takes a few minutes with `domain: complex`, but
less than a second with `domain: real`. (It does correctly return 1 in
both cases.) Maybe we should try to find out if we can disable this
`domain: complex` setting in Sage for some things...
