Space in single owner name treated like multiple owners

[dcheckoway]

Our CODEOWNERS file has entries like:

src/foo/bar/                @"Bar Tender"
src/foo/baz/                @"Nuther Guy"

Despite the quotes, these names are being split apart, and they show up as multiple (2) owners. See these screenshots:

It would be "A Mazing" if you could honor quoted strings as a single name. Thanks in advance!
