Fancy select (picker) and append

[Bekt]

Fancy select is "correctly" displayed on Safari, but not on Chrome/Firefox when it is used in an .append form. I tried fixing this myself, but couldn't get far. See the screenshots below. Although Safari correctly displays, it messes up after an option is selected.

Code:

<div class="append field">
  <input class="xnarrow input" type="text" />
  <div class="medium primary btn"><a href="#">Go</a></div>
  <div class="picker">
    <select>
      <option>1</option>
      <option>2</option>
    </select>
  </div>
</div>

Chrome/Firefox:
