#10366 details a bug with the new implementation of the weighted round robin earliest deadline first scheduler, StaticStrideScheduler.
This bug was fixed by properly scaling the mean weight in the edge case where all subchannel weights are invalid and making sure they have correct casting and rounding logic. An assert statement was added to check for cases with many passthroughs and test cases were also made to be more strict to better verify behavior.
