1.26 +/*
1.27 + * Inspired by review comments on bug 378217.
1.28 + *
1.29 + * The original idea was to test that ExpectEndProperty calls are made
1.30 + * in the correct places in the CSS parser so that we don't accept
1.31 + * garbage at the end of property values.
1.32 + *
1.33 + * However, there's actually other code (in ParseDeclaration) that
1.34 + * ensures that we don't accept garbage.
1.35 + *
1.36 + * Despite that, I'm checking it in anyway, since it caught an infinite
1.37 + * loop in the patch for bug 435441.
