Description

For the options like "Deallocated memory" + "Deallocation sites", it's not easy to find out what they mean.

We have a tooltip though! It's on the <option>. But you only see the tooltip while the <select> menu is open.

I think we should add the description of the selected option to the <select> itself too, so that you get a tooltip when the menu is closed.
