> If the source contains too little data (rounds the result down to 0), or if size estimation fails, then we don't call .split(). We must always call split(); instead of returning original source, we should have computed some fallback value for desiredBundleSize.
> This bug has existed since the code was first introduced, so it is not a regression - but it is certainly a bug.
