Make it clear that "Restart Style" is a drop-down menu

Hello!

I'm using xfce4-session 4.14.2 (Xfce 4.14) on Ubuntu 20.04.1 LTS.

After following the documentation I learnt that the "Restart Style" on "Session and Startup" > "Current Session" is a drop-down menu which is absolutely unclear looking at the UI.

"Program" and "Restart Style" looks identical and user has no way to know that "Restart Style" is configurable drop-down menu.

May be we can use standard xfce drop-down menus like these?
