Laying out LTR text within RTL is really under the control of the browser. There are some things that can be done, but this is just a single run of text, so what you're display seems like a bug in Chrome. Can you provide an example URL?
Note that the specifications for how "weak" characters are handled (which is what parentheses are) are quite complex (http://unicode.org/reports/tr9/). It's possible that Chrome is actually correct here. I'm not positive if the icon that's been added (using Font Awesome I assume) is affecting anything as well.
