Freeze on IE when focusing on an item

[KatieWoe]

Test device:
Dell
Operating System:
Win 10
Browser:
IE
Problem description:
For phetsims/qa#311. When focusing on a circuit item to change it's resistance or voltage, the sim freezes and must be refreshed. Does not occur for items like the wire where a trash button is the only thing available. So far only seen on IE, but it makes the sim unusable.
Steps to reproduce:

1. Grab a battery, resistor, or fuse
2. Click on the item so that a slider that would control some property would come up
3. The sim will now no longer respond to any clicking and must be refreshed.

Is this problem also in the published version?

[KatieWoe]

No it is not.

[samreid]

Is an error message reported in the console?

I pushed a proposed fix to address phetsims/scenery-phet#493, however, it cannot be tested with assertions enabled because some assertions in our codebase use Array.prototype.includes. So I've published a dev version for testing this: https://phet-dev.colorado.edu/html/circuit-construction-kit-dc/1.1.0-dev.4/phet/circuit-construction-kit-dc_en_phet.html

@KatieWoe can you please check if it is OK now?

Problem seems to be solved there @samreid

Thanks, I'll close this issue.
