Description:

combineLatest was mutating the array of observables passed to it. This is a very simple fix to clone the array before modifying it.

See this codepen for example of the problem: https://codepen.io/anon/pen/qRNBVJ?editors=1111

@extremeandy ... good catch. This looks like a side-effect from the time we added the ability to do both combineLatest(a, b, c) and combineLatest([a, b, c]) (originally it was just the former, which used rest arguments).

LGTM! 👍
