CT: no item found that has focus (ComboBoxListBox)

[pixelzoom]

This has been popping up (pun intended) in geometric-optics, a problem with focus in ComboBoxListBox. I don't know if it's happening in other sims. @jessegreenberg @zepumph thoughts?

This is not a sim-specific issue but a general problem with headless Chrome and CT. It started showing upbecause we improved testing coverage in phetsims/scenery#1379 recently. But it is happening because certain DOM events that we rely on do not fire in headless Chrome.

?fuzzBoard had been effectively disabled on CT until we can address this.

Reassigning to @pixelzoom so he is aware but I think this issue can be closed.
