// A rustdoc bug caused the `feature=bar` syntax for the cfg flag to be interpreted
// wrongly, with `feature=bar` instead of just `bar` being understood as the feature name.
// After this was fixed in #22135, this test checks that this bug does not make a resurgence.
// See https://github.com/rust-lang/rust/issues/22131

//@ ignore-cross-compile
// Reason: rustdoc fails to find the "foo" crate
