After talking with Glen some more we agreed that it would be better to drop the
special mouse-handling on this icon and just make it a purely graphical
indicator.  Clicking on it will be no different than clicking anywhere else on
the line.  That should simplify some code.

I think maybe this code didn't draw the appropriate background color behind the
icon when the rest of the line was selected/hovered anyway?, so if so, that will
get automatically fixed too.

Nit: If one arm of a conditional spans more than one line, you need {}.

You might be able to prevent this by factoring out all the
popup_model_->edit_model() calls to a temp?
