The description is useless (this isn't even V8 bug 16127, I have no idea where
it's from).

Consider either removing all descriptions, or adding a comment above saying that
this is taken from somewhere else (and, if possible, link to where it's taken
from), and that text in the tests does not refer to the Dart project.
