Related to 7730.

If Firefox decides to mangle the offset values there isn’t a lot that can be done. In any case, it’s not something that we are probably going to spend time on. Feel free to submit a patch that works consistently across all browsers without causing trouble with devices that support sub-pixel precision and we would be happy to consider it.
