Should there be a range or error message when changing positionProperty values?

Problem description
For phetsims/qa#938, I am noticing 2 odd things in studio when using the 'get value' 'set value' buttons for positionProperty:

1. For lensScreen.model.scenes.arrowScene.arrowObject1.positionProperty, I am able to enter a positive x value which moves the arrow to the right side of the lens. Once I either try to move the arrow, or launch the sim, the x value changes to -40.

2. For lensScreen.model.scenes.framedScene.framedObject.positionProperty, if I enter a value larger than -40, the object is placed at x= -40. The same is true for the lightScene. I was wondering if an error message should pop up or if a range should be given here?

Steps to reproduce

1. In studio, go to lensScreen.model.scenes.arrowScene.arrowObject1.positionProperty and press 'get value'
2. Change the value of x to a positive number. Press 'set value'
3. Try to move the arrow
4. Repeat steps with lensScreen.model.scenes.framedScene.framedObject.positionProperty

Thanks @Nancy-Salpepi. This came up in #454 (and other sims linked in that issue too) and we decided to do nothing. Validating positionProperty is far more complicated than validating a simple number like diameterProperty. In examples.md, we recommend that clients set the desired position by interacting with the simulation and using "Get Command".
