Version compatibility issues

Hello, using an older version of fastdom (0.8.6) throws an error with read and write methods when overridden by bowser or website's newer version of fastdom - they're replaced with measure and mutate. Is there a workaround you'd suggest to make the older version not break?

Here's an example: https://jsfiddle.net/10hn9hd6/ Browser used: Chrome 51.0.2704.103 (64-bit)
