Description
Currently partition will subscribe to whatever observable you get twice. Given that it is supposed to "partition", which sounds like splitting one thing into several parts, I'd think it should multicast the source.
ALSO: The partition operator just needs to be removed in favor of groupBy, as it doesn't make any sense as an operator with pipe.

Research direction
Start by locating the partition and groupBy entry points in the TypeScript source, then inspect how partition is used with pipe. Done means the project has a decided resolution—either the subscription behavior is corrected or the operator is removed in favor of groupBy—and tests document that outcome.
