This one is failing because the new attr fallthrough behavior in v3: vuejs/rfcs#26
There is no longer automatic class merging and the child now needs to explicitly merge parent props.

The only difference between the 2 cases is that child2 has an empty props declaration, therefore it successfully triggered class merging while the other one didn't.
I didn't see anything about this behavior in the inheritAttrs RFS.
Seems a bug in the current implementation?
