layoutUnit header problem in webkit

[pixelspop]

When using a p:layout I removed the header attribute from the left p:layoutUnit component. This component still had collapsible="true" and rendered nicely with a collapsible button in a small title bar with no text under Firefox and IE. However, under Chrome/Safari/Webkit the left unit does not display the little title bar and consumes 100% of the browser's real estate. No other p:layoutUnit sections were accessible.

I workaround the issue by adding header=' " to the lef p:layoutUnit. I don't think I should have had to do this though.

Should this get logged as a bug?

Versions 2.1 and 2.2 RC2.
