Is serverSideTabSwitch="true" required when using validation with ?

[Paul Spencer]

I have a form on a tabbed pane that validates input. When their is a 
validation error and the attribute serverSideTabSwitch on 
<t:panelTabbedPane> is undefined or set to false, the first tab is 
displayed, not the one with the error.

Is this the expected behavior or a bug?
