Ember 3.22.0 double compute issue in version 14.x

[robclancy]

You can reproduce with your own tests. Just checkout version 14 and run tests.

Uncaught Error: Assertion Failed: You attempted to update `tabIndex` on `SelectBox`, but it had already been used previously in the same computation.  Attempting to update a value after using it in a computation can cause logical errors, infinite revalidation bugs, and performance issues, and is not supported.

`tabIndex` was first used:

Stack trace for the update:
    at setter (validator.js:833)
    at SelectBox.set [as tabIndex] (index.js:3908)
    at enable (disabled.js:23)

I checked out the 14x tag and updated to Ember 3.22.0. It does output a load of:

DEPRECATION: You attempted to update `tabIndex` on `SelectBox`, but it had already been used previously in the same computation.  Attempting to update a value after using it in a computation can cause logical errors, infinite revalidation bugs, and performance issues, and is not supported.

`tabIndex` was first used:

- While rendering:
  application
    index
      select-box

...but all the tests pass.

Do you have any more details for how to make it error, like your example

That's because they changed it in 3.22.2 and you must have tested that version.
