Regex/Javascript syntax highlighting bug

I am using regex to validate an email input field as described here: http://www.regular-expressions.info/email.html

When I use that regex in my javascript, the syntax in rest of my document after the regex is incorrectly highlighted. Try copying and pasting the following code into a javascript file.

if($('form.contact input.email').val() == '' || !$('form.contact input.email').val().match(/[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/)) {

        hasError = true;

        $('form.contact input.email').addClass("error");

        console.log('Email is at fault');

}

Is anyone else having this issue? I am using ST3, pretty sure it does it in 2 as well.
