The incorrect value has always been used for the `beforeTwoEighteen` variable. However, this is not actually a problem because the `beforeTwoEighteen` variable is not necessary. It's only job is to prevent newer versions from sending extra data to older versions. However, older version will simply ignore the extra data which means the `beforeTwoEighteen` variable can be removed completely. This same compatibility pattern is used in many places for the Core protocol. The tests added with the original fix successfully reproduced the original problem and those tests still pass even with this variable removed. Also, keep in mind that `decodeRest` is still checking the version so that it doesn't try to read data that doesn't exist from an older version.
