  1. Failing useMutableSource test 

    If a source is mutated after initial read but before subscription is set
up, it should still entangle all pending mutations even if snapshot of
new subscription happens to match.

Test case illustrates how not doing this can lead to tearing.

    Fix is to move the entanglement call outside of the block that checks
