Vertical-alignment issues with Helvetica Neue
===

This is a minor but persistant annoyance with Helvetica Neue (doesn't happen w Arial)

Text that is perfectly vertically aligned will shift downward slightly when any part of the text is bolded. While it's a small shift, it ruins alignment when mixing bold and non-bold text elements side by side. 

See [http://jsfiddle.net/ZZ3m6/7/][1] for example.

Even when explicitly setting line-heights, the shift occurs. How can I stop this?
