Research direction

Start with the unit test containing test("explain comet") and inspect how supportsExtendedExplainInfo currently controls the check. Separate the Spark-dependent extended-info coverage from the Spark-independent test, ensuring the dependent test runs only for Spark 4.0 and later; the existing tests should then pass without the conditional in the independent part.

Separate out extended explain info unit test into spark dependent and spark independent parts

Steps to reproduce

No response

Expected behavior

No response

Additional context

The test test("explain comet") has a conditional check which executes only if supportsExtendedExplainInfo is true. This can be moved into a separate unit test that is run only for Spark 4.0 and greater which actually support extended info.
