Add tooltip to label in UI wizard in GUIs

My camel addon builds some commands that has ui steps where the end user can enter some details. As we have documentation for each of those input fields what they mean, they are currently shows as tooltip.

The tooltip is only shows in the input field, eg see screenshot of eclipse.

In IDEA then the tooltip only works on some input fields like boolean types. But for the general text based inputs its not shown.

I wonder if we could add tooltip to the label also? so you can however over the label (eg Period, then it would always work there.
