// Fallbacks from external URLs (such as HTTPS URLs) are
// blocked by ongoing spec discussions, for example
// https://github.com/WICG/import-maps/issues/76.
// https://crbug.com/928435
//
// This test, as well as Chromium's implementation, rejects broader range of
// fallbacks (not only those from HTTPS), to avoid potential spec and
// interoperability issues.
// The only allowed fallback pattern is fallbacks from bare specifiers with
// two elements, which are listed in fallback.sub.tentative.html.
