Workspace Bug - Chrome - Passing object as param (ES6 syntax) breaks indent

Was able to duplicate this repeatedly with a simple step.

Take this code from ES2015 Workshop for example

'use strict';

class Student {
  constructor({name, age, interestLevel = 5} = {}) {
    this.name = name
    this.age = age
    this.interestLevel = interestLevel
  }
}

The object passed here: 

constructor({name, age, interestLevel = 5} = {})

will result in the indent changing from 2 to 15 for tab and the return position on each new line being at 15 spaces, as well.

Removing this object and doing something like 

let props = {name, age, interestLevel = 5} = {}

results in the same behavior. In fact, passing anything in the object at all other than improper syntax such as {name: bob} (improper in this context anyway) results in said behavior.

I've produced this issue in Chrome Version 55.0.2883.95 (64-bit) on macOS 10.12.2.

Note that this also breaks syntax highlighting; key values like name go from orange to green highlighting, so this probably has something to do with whatever library you're using for the syntax highlighting.
