Have you tried simply relaunching Safari after Simulator starts running?
I find that Simulator is always in Safari's Develop menu if it's already running when Safari launches, and Simulator is never in the menu if Safari is launched first. That's Simulator 10.0 (comes with Xcode 8.1), Safari 10.0.1 and OS X 10.11.6.
先運行模擬器并鸵，再打開Safari 即可鸳粉。
