Describe the problem

isEqual doesn't work on arrayUnion, arrayRemove, and increment. They always return false, even when they are equal.

Steps and code to reproduce issue

console.log(arrayUnion().isEqual(arrayUnion()));//return false
console.log(arrayRemove().isEqual(arrayRemove()));//return false
console.log(increment().isEqual(increment()));//return false

Thanks for reporting this. I investigated and found some old TODOs in the code for these isEqual methods. I've opened a new internal feature request to get this implemented.
