> If the planner merges two sets when they have been determined to be equivalent, the RuleMatchVisualizer does not merge them in the visualization. Instead, it keeps the second set with the subsets but no RelNode inside.
> To reproduce the issue, apply the RuleMatchVisualizer to VolcanoPlannerTest.testSetMergeMatchSubsetRule(). The set-2 should be merged into set-0, and the subset#11-set#2 into subset#12-set#0:
