Problem description
phetsims/qa#724
This is not a major issue, but I thought I would report anyway.
When the Normal Mode Spectrum accordion box is collapsed, remnants from the frequency values are still visible.

Steps to reproduce

1. Select the One Dimension Screen
2. Optional: Increase the Number of Masses
3. Collapse the Normal Modes Spectrum accordion box

The good news is that this doesn't require an M1 device to reproduce. I can reproduce on my Intel MacBook Pro (16" 2019) with macOS 12.01 + Safari 15.1 (17612.2.9.1.20).

It's interesting that the artifacts are part of the subscript of ω₀.

This is another one of those "scenery artifacts" that can't be easily resolved. I could try a different renderer. Or we could just ignore it for the prototype.

@jonathanolson recommendations?

@pixelzoom I think this is minor enough to ignore for the prototype, but I still think it would be good for @jonathanolson to review since it could be relevant to other sims.

OK. Will not address for the prototype. Labeling as deferred until someone works on this sim for public release.
