Dialog title as html not handled properly using option setter

[jvivs]

affected versions: -jquery: 1.5.1 -jquery ui: 1.8.16

browser: chrome 14.0.835.163

OS: OSX 10.7.2

Reproducable by setting an existing dialog's title via the options setter. Ex:

<div class="dialog">Dialog? Yep!</div>

<script>
var dialog = $('.dialog').dialog();
dialog.dialog('option', 'title', $('<span style="color: red">I\'m a title and I\'m OK</span>'));
</script>

Results in the title being set to [Option option] when the jQuery object is converted to a string on line 595 of /jquery-ui/ui/jquery.ui.dialog.js as of a0856efef3c392d413aa6cd9bd084dc601a337c6.

That's not HTML, that's an object.
