Voltage text box moves when zoom in/out

[ghost]

Test device:

MacBook Air (13-inch, Early 2015)

Operating System:

macOS Sierra 10.12.6

Browser:

Safari 10.1.2

Problem description:

While testing the CCK DC, I noticed that the text box for the voltage on a battery can move when one zooms in if the circuit is large, the battery has been flipped upside down and is on fire. This is for phetsims/qa/issues/48.

Steps to reproduce:

1. Zoom out.
2. Check the "Values" box.
3. Put a battery in the center of the screen.
4. Connect a wire from the negative terminal to the upper left corner of the screen.
5. Connect a wire from the positive terminal to the lower right corner of the screen.
6. Complete the circuit by connecting another wire to the loose ends of the other two wires.
7. Flip the battery.
8. Zoom in.

@lmulhall-phet did you see the "schematic" radio button flickering? Should that be a separate issue?

@samreid that's just a side-effect of the screen-recording app being used. The sim was never actually flickering, only the .gif file flickers.

Co-assigned to @arouinfar and @ariel-phet to help gauge priority for 1.0.

[ariel-phet]

@lmulhall-phet nice find! That is some @phet-steele level work

@samreid this is definitely an edge case, no need to investigate for 1.0 . Marking as deferred.

@ariel-phet I found the issue while messing around with a huge, complex circuit, but @phet-steele was able to reproduce the issue with a simple circuit. (He deserves some credit.)

In master on Chrome, the voltage text box now travels with the battery in this scenario. Closing.
