When outline is set to none or 0 it's impossible to revert back to the UA default. By just setting outline-width to 0 I can at least set it back to 3px which gives the correct default border in Chrome. I believe Firefox uses a 2px border so it might be a little chunky but better than having to totally recreate the outline styles for different platforms. Thanks to @atotic for the tip!
