Cursor in uneditable ComboBox

Vaadin 6.7 introduces the new setTextInputAllowed(false) method to ComboBox. This is a very good idea and I would like to use ComboBox instead of native selects everywhere. However, (at least in Firefox), it shows a movable non-blinking cursor when the combo box is focused. I think that this is not acceptable from a user perspective. Is there a way to get rid of this cursor? If not, is this planned for a future release?
