title: Autocomplete window placed too high
body: <p>I've got a jQuery UI autocomplete menu that is initially showing up too high and blocking the textbox. After a few more keystrokes, though, the box will move down to its proper position. Anyone ever run into this and know how to fix it, or is it a bug in jQuery-ui? The only other instance I can find of this is a bug entered <a href="http://bugs.jqueryui.com/ticket/6636" rel="nofollow noreferrer">here</a> about two years ago that has been closed and marked for deletion. I get this in Chrome 26 and IE 10, but not Firefox 20.</p>
