// Bug 1247004
//
// The Web Animations polyfill had a bug that translated 'linear' into
// the string 'function (a){return a}'. This bug has been fixed but older
// versions of the polyfill are still widely used. Google are collecting
// usage data on this but for now we need to *not* throw on
// 'function (a){return a}' or else a lot of sites will break.
//
// Instead, we should treat this string as equivalent to 'linear' and
// return Nothing().
//
// Chromium has a similar special case path for this string.
// See: https://bugs.chromium.org/p/chromium/issues/detail?id=601672
if (aEasing == NS_LITERAL_STRING("function (a){return a}")) {
