Test Runner Not Detecting Equal Lists on Interval<Time>

When running the test CqlIntervalOperatorsTest:Expand:ExpandPerHour, the test runner reports:

Test CqlIntervalOperatorsTest:Expand:ExpandPerHour status: fail expected: { Interval[@T10, @T10], Interval[@T11, @T11], Interval[@T12, @T12] } actual: [ [Object], [Object], [Object] ]

My engine is returning { Interval[@T10, @T10], Interval[@T11, @T11], Interval[@T12, @T12] } and translating it to a list of Tuples since the CQL IG FHIR type mapping doesn't have a specific mapping for Interval<Time> (and since Period represents start/end as dateTime values):

Given the current guidance on mapping, this is the best way to represent a list of Interval<Time>.

Start with the CqlIntervalOperatorsTest:Expand:ExpandPerHour case and trace how the test runner compares its expected Interval list with the returned Parameters representation. Check how the list of Interval tuples is parsed or displayed, then confirm that equivalent values are recognized as equal and the test passes.
