LoL sends balloon further when sim is paused while balloon is moving

[KatieWoe]

For phetsims/qa#721.
When the sim is in the LoL harness, if you pause while the balloon is drifting towards the sweater, then the balloon goes further when you unpause than it would if you hadn't paused.

@KatieWoe - Is this issue unique to this RC version or does it exist in the currently published version?

It does happen with the published version.

I discussed this with @emily-phet, and she and I decided that I should take a quick look at this and fix it if it's easy, defer it if not. It turns out that the link to the LoL harness is no longer in the QA issue because it's behind a password, the QA lead doesn't know what that password is, and it's not listed in the credentials document for level 2, so just trying to figure out how to duplicate the issue has already blown my budget for investigating it.

Also, I asked @KatieWoe about how she was pausing it so quickly in the GIF she captured, and she said she was using a touch device. So, the combination of the sim being in the LoL harness, balloon charged and moving, paused quickly in mid-motion, and the outcome just being slightly different than if it hadn't been paused - it all creates a picture of a low likelihood situation that is also low severity. Based on this, I'm going to make a call that this issue should be labeled as "won't fix" instead of deferred and closed.
