> In Analytics, certain QuickTheory tests are flaky. The seeds are logged for
> the failed tests. However, the random values are produced from the multiple
> randomness sources, rendering the logged seed useless.
> Proposing this patch to wire all the randomizers to the single source, in
> order to reproduce the failure deterministically in the offline run.
