standard wrapper doesn't show path when launched #455

Test device MacBook Air (m1 chip)

Operating System macOS 12.6

Browser safari and chrome

Problem description For https://github.com/phetsims/qa/issues/838, when the sim is launched from studio the planet/moon/satellite are in the correct position in the standard wrapper, but the path that was previously taken is missing. Seems similar to what was reported back in https://github.com/phetsims/gravity-and-orbits/issues/335.

Steps to reproduce

  1. Pick a scene on either screen
  2. Check the path checkbox
  3. press Play
  4. after the planet/moon/satellite has moved a bit, press Pause
  5. press Test button

Oddly, it will appear in the launched sim if you hit the scene reset button.

@samreid I just wanted to confirm the behavior of the Restart button in this case: After following the above steps, and then pressing play, pressing the Restart button erases the path (Pressing Reset or Reset All buttons return the path the screen).

That sounds correct to me, because the Reset scene or Reset all is meant to restore the initial PhET-iO State. But the Restart button is supposed to go back to the initial conditions for the last experiment, which would have path lengths of zero.

Great! Then this can be closed!
