A problem with neo4j's db.schema()?

UPDATE: tl;dr: db.schema() is broken, use apoc.meta.schema() instead.

I have the following sample cypher, creating some nodes and some relations:

CREATE
    (footypeA:Footype {name:'FootypeA'}),
    (fooA:Foo  {name:'FooA'}),
    (fooB:Foo  {name:'FooB'}),
    (bartypeA:Bartype  {name:'BartypeA'}),
    (bartypeB:Bartype {name:'BartypeB'}),
    (barA:Bar {name:'BarA'}),
    (barB:Bar {name:'BarB'}),
    (fooA)-[:HAS_TYPE]->(footypeA),
    (fooB)-[:HAS_TYPE]->(footypeA),
    (barA)-[:HAS_TYPE]->(bartypeA),
    (barB)-[:HAS_TYPE]->(bartypeB);

This gives us some nodes and relations as in the image below, in the top section:

But why, oh why, does the call to db.schema in the bottom section show us some ackward meta schema? Why does neo4j think that there is a "has_type" relation from a Foo to a Bartype? I mean, everybody knows that foos and bars are different things...

This is on neo4j-community-3.3.5.

UPDATE: And it turns out, this is a long known bug:

https://github.com/neo4j/neo4j/issues/9726

Workaround:

call apoc.meta.graph()

Silly me, I should have looked up the bug in the first place. Or maybe neo4j should have fixed it? Or changed their documentation?...
