Chips can overlap with touch

Safari

Problem description
For phetsims/qa#1014 on the Chips screen, if I use 2 fingers to add 2 positive (or negative) values to the bag at the same time they will move to the same spot when I let go. This is also seen in published.
Assigning to @marlitas and @amanda-phet to decide on whether or not to defer.

Steps to reproduce

1. With the iPad on the chips screen, grab 2 positive values with 2 fingers.
2. Release them in the bag at the same time.

@amanda-phet and I talked about this issue and I will move forward with a quick investigation. If a fix seems easy with minimal code disruption we'll move forward, if not we will defer to a future publication.

I've passed the allotted time in exploration. This becomes even trickier to diagnose for me because the only touch device I have is my phone, and I'm having a tough time finding a reliable way to console.log to that device to dig into the specific situation.

This is not straightforward from looking at the code and is outside the scope of the region and culture publication. Deferring.
