@erights please take a look to the small change I added, and to the test, I cannot add you as an official reviewer since you opened the PR. |

Description
#9719 originally failed on upgrade replay for an endowment. It revealed a bug introduced to async-flow when adding support for endowments. Because of the so-called "unwrapping" of some guests, there can be two guests corresponding to one host, with the host of course only mapping back to one of them -- the outer one. This makes
bijection.jsmore complicated and irregular than an actual bijection.equate(g, h)had a test for early return, if thegandhwere already "equated", i.e., were corresponding guest and host. But the equate test was written before the elaboration of bijection. In fact, it should only test whether this guestgmaps to the hosth, irrespective of whetherhmaps back to thisg.Additional testing revealed that the unwrapped function was also not passable, and would fail to be passed back as an argument.
Security Considerations
None
Scaling Considerations
None
Documentation Considerations
This change potentially makes the diagnostic error when misusing async-flow slightly less precise.
Testing Considerations
Introduces equate checks in the endowments test exercising the bijection. For endowments with are further "unwrapped", we test both the original guest (which was previously failing) and the unwrapped one (which also was, but for a different reason).
Since #9719 landed with a failing test, this PR also sets that test as passing, effectively working as an integration test of functions as endowments.
Upgrade Considerations
Can be deployed as a new version of the async-flow NPM package.
