What information was incorrect, unhelpful, or incomplete?

The documentation does not mention IDN domain names at all! It says that it's an USVString and mentions Unicode, but it's NOT unicode. It's the IDN translated name, which might come as a big surprise to anyone using IDN domains.
This problem goes for all properties of the Location object.

Specific section or headline?

What did you expect to see?

At least it should be mentioned clearly!

Did you test this? If so, how?
