If you have text next to a select box and the initial option for the value is empty, then webkit misaligns the text when you click the select box. Changing it to an option with text is correct and changing it back to the empty misaligns the text. Using a non-breaking space resolves the issue, but the issue didn't exist in Safari nor does it exists in Firefox and IE.
