Buggy behaviour with TreeTable setSelectable

Hi,

when I set my TreeTable (or Table) to setSelectable(false) when there is already a selection and hover over the selected item it goes from a normal looking blue row to a clear row with nearly completely transparent text.

This code should drop in and replicate the behaviour on Vaadin 6.7.6, Tomcat 7.0, IE 8.0

Is this a legit bug and how should I raise it?
