I understand why it happens:
Lines 477 to 478 in 6aa9047
I don't know how to fix it though. There are cases where we want to follow the protoype and other where we don't, but I'm not sure V8 gives us enough information to know in which case we are. |
Maybe the solution is to set a NamedPropertyQueryCallback (we currently don't). |

What steps will reproduce the bug?
Tested in both v22.0.0 and v20.12.2.
How often does it reproduce? Is there a required condition?
No required condition.
What is the expected behavior? Why is that the expected behavior?
Either the property is present or it is not. So either
{ hasOwn: false, descriptor: undefined}
and{ hasOwn: true, descriptor: { ... } }
would be better.What do you see instead?
{ hasOwn: true, descriptor: undefined }
