Problem description For https://github.com/phetsims/qa/issues/1150 and also in published, on the Single Bulb screen I'm finding the behavior of the sim to be a bit confusing when the sim is paused. I guess it is because the, moving the slider thumb will change the color of the beam when the sim is paused, but will not update the the color of the photon stream until play is pressed.

Here is an example:

  1. Turn on the flashlight
  2. Select white light
  3. Switch to Photons and then back to Beam
  4. Press Pause
  5. Turn off the flashlight --This will turn off the beam and change the think bubble to black
  6. Switch to photons--The stream of photons will still be there and the think bubble will still show white
  7. Press Reset all
  8. Repeat the above steps but SKIP step 3 --when completing step 6, the stream of photons will still be there but the think bubble is black.

I am guessing that nothing will probably been done, but I wanted to note this for the record.
