Using jQuery UI 1.8.10 themes with Yii 1.1.6

When using the latest stable jQuery UI themes (1.8.10) with Yii 1.1.6 (which uses 1.8.6) the widgets don't appear (they're invisible but they're there). In order to make them visible you need to change the following line:

[css]
.ui-helper-hidden-accessible { position: absolute !important; clip: rect(1px 1px 1px 1px); clip: rect(1px,1px,1px,1px); }

to:

[css]
.ui-helper-hidden-accessible { position: absolute; left: -99999999px; }

The widgets won't look perfect (for which you need to play around some more) but they'll at least be visible.

I hope this saves someone's time.
