Sometimes named hooks inspection will seemingly fail the first time then work the second time. (e.g. using a DEV build of Facebook.com, the `<CometTheme>` component currently does this).

I _think_ this might indicate a timeout during inspection? (So the retry is fast because everything is cached.)
