message objects inherit nulls from prototype when using defaults:false

[dvisztempacct]

protobuf.js version: 6.8.6

When using defaults:false option, I'm seeing null values in inherited properties corresponding to fields when I inspect the return values of decode or toObject.

I had been under the impression that I would get undefined instead, but that doesn't seem to be the case.

There's an older issue #658 that seems to describe my situation exactly.

Maybe I'm just doing something wrong?

Thanks for protobufjs!
