Waves look odd when the wall is moved while paused

[Nancy-Salpepi]

Test device MacBook Air (m1 chip)

Operating System 13.5

Browser safari 16.5

Problem description For https://github.com/phetsims/qa/issues/974, this might be outside the scope of this release, but it looks really odd to me that the wave doesn't disappear/update when the wall is moved during pause.

Steps to reproduce

1. Go to the Reflection Screen and pause the sim after waves have reached the wall
2. Move the Wall Angle slider all the way to the right
3. Press play and then pause again
4. Move the Wall Position slider all the way to the right

What is really interesting is....if I take a screenshot from the PhET menu, it shows the "updated" wave. Here is what the screen looks like:

It also "updates" in the other direction. Here is the screen:

I see something similar with the screenshots when moving the speaker while paused on the Two Sources Screen. Steps:

1. On the Two Sources screen wait a couple of seconds and then press pause
2. Move the speaker to the top of the play area
3. Take a screenshot

What it looks like in the sim:

This has been fixed on main and ready for spot-check! Both the 2-source and the reflection screens show updated waves when changing properties while the sim is paused.

Looks ok to me on main.

This looks great now!

Looks good in rc.2! Closing.
