I guess we should break the loop here.

Hmm, the original code does actually visit non-SymbolData.

Fix visitation, add early termination, add comments

I believe you're correct, the original code terminates early because of the short circuit evaluation on line 553, and visits all reachable nodes but doesn't recurse on non-SymbolData.

Yep, looks correct now :)
