------------------------------------------------------------------
In the example, #10-PhysLeafRel appears out of the blue in the FINAL step. Good
opportunity to check why this is the case.
Another minor thing to fix: if there's a ?step=33 argument, nothing is viewed
because of an error: data.steps[prevStepIndex] is undefined.

> 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:
