Invalid dialog position in Opera

[Trustmaster]

If the page is long enough, if you scroll to the bottom of it and open a dialog, it appears on the bottom of the page (sometimes even out of the viewport) no matter what position you specified.

Example code:

$('#smilies').dialog({
			title: L.smilies,
			height: smileBox.height,
			width: smileBox.width,
			position: ['center', 'middle']
		});

Tested in Opera 9.5.x/9.6.x, jQuery UI 1.5.3 and 1.6.rc5. Works fine in Firefox and other browsers though.

Well, after I switched to jQuery 1.3.1 the problem disappeared, so the ticket can be closed now.
