Mouse click remains when touch screen used

[KatieWoe]

Test device:
Dell Laptop
Operating System:
Win 10
Browser:
Chrome
Problem description:
Found during phetsims/qa#212, but not restricted to that sim.
When holding something with the mouse, if the touch screen is used during that time the mouse can be released but acts as if it is not. Assigning to @jonathanolson as it looks like an input event issue.
Steps to reproduce:

1. Go to States of Matter's second screen
2. Use the mouse to turn on the heat bucket. If the mouse is released, the heat bucket turns off.
3. While using the mouse to keep the heat bucket on, use the touchscreen to move the roof of the container
4. While using the touch screen release the mouse. The heat bucket should stay on.
5. After this you can let go of the touch screen and the heat bucket will stay on.

Is Hanson the device that exhibited this problem? I might wait until Tuesday to investigate this in person.

@jonathanolson, I think the device Katie used is a similar model to Hanson. It's essentially a larger version of Hanson.
