It appears that the ORDER BY rank operation is the slowing factor.
If I remove it then the query is pretty fast. Is there another way
to perform ORDER BY such that it does not do a sort?

I think you misunderstood: it's not the sort that's slow,
Oh, I see. I didn't look carefully at the EXPLAIN ANALYZE I posted.
So, is there a solution to the rank problem?
