Humming continues if you switch screens

[KatieWoe]

Test device Samsung Operating System Win 11 Browser Chrome Problem description For https://github.com/phetsims/qa/issues/993 When the screen is changed while the interval tool's hum is still playing, the sound continues as a consistent hum until the Variability screen is returned to. This was seen/heard during fuzz tests as well. Steps to reproduce

1. Go to the variability screen and turn on the interval tool
2. Drag one of the ends of the tool to create it's sound
3. Before the sound ends, switch screens. This needs to be done quickly, but is relatively easy to do.

Worked on a good solution with @zepumph. This issue is now ready for cherry-pick.

Looks good in rc.2
