I think it'd be better to add a new test for this, rather than modifying the existing test.
In effectScope.ts, there's this if check:
if (last && last !== this) {That line is only hit once by the tests. Currently it evaluates to false. The change proposed here would switch that, so it evaluates to true. That increases the line coverage, but it's still only testing one of the two branches of the if. Either way there's a chunk of code that could be removed and the tests would still pass.
For example, imagine that if check were changed to this:
if (last) {That would be incorrect and the existing test would catch that, but the new test would still pass.
