Form validation issue with 1.7.6

Current behavior:

I have a form with 2 fields (one input and one textarea, input is required, and textarea is not). On 1.7.6 when I display page with that form the textarea is marked as required (if I focus on it and then click outside the error message is displayed). After entering any text the error is gone, and textarea is no longer required (I can clear any text and no error is shown). With 1.7.5 and below this works as expected.

Here is the form object when page is rendered on 1.7.5:

{
  "$error": {
    "required": [
      {
        "$validators": {},
        "$asyncValidators": {},
        "$parsers": [],
        "$formatters": [
          null
        ],
        "$viewChangeListeners": [],
        "$untouched": true,
        "$touched": false,
        "$pristine": true,
        "$dirty": false,
        "$valid": false,
        "$invalid": true,
        "$error": {
          "required": true
        },
        "$name": "username",
        "$options": {}
      }
    ]
  },
  "$name": "userForm",
  "$dirty": false,
  "$pristine": true,
  "$valid": false,
  "$invalid": true,
  "$submitted": false,
  "username": {
    "$validators": {},
    "$asyncValidators": {},
    "$parsers": [],
    "$formatters": [
      null
    ],
    "$viewChangeListeners": [],
    "$untouched": true,
    "$touched": false,
    "$pristine": true,
    "$dirty": false,
    "$valid": false,
    "$invalid": true,
    "$error": {
      "required": true
    },
    "$name": "username",
    "$options": {}
  },
  "description": {
    "$validators": {},
    "$asyncValidators": {},
    "$parsers": [],
    "$formatters": [
      null
    ],
    "$viewChangeListeners": [],
    "$untouched": true,
    "$touched": false,
    "$pristine": true,
    "$dirty": false,
    "$valid": true,
    "$invalid": false,
    "$error": {},
    "$name": "description",
    "$options": {}
  }
}

Below the same page but with 1.7.6:

{
  "$error": {
    "required": [
      {
        "$validators": {},
        "$asyncValidators": {},
        "$parsers": [],
        "$formatters": [
          null
        ],
        "$viewChangeListeners": [],
        "$untouched": true,
        "$touched": false,
        "$pristine": true,
        "$dirty": false,
        "$valid": false,
        "$invalid": true,
        "$error": {
          "required": true
        },
        "$name": "username",
        "$options": {}
      },
      {
        "$validators": {},
        "$asyncValidators": {},
        "$parsers": [],
        "$formatters": [
          null
        ],
        "$viewChangeListeners": [],
        "$untouched": true,
        "$touched": false,
        "$pristine": true,
        "$dirty": false,
        "$valid": false,
        "$invalid": true,
        "$error": {
          "required": true
        },
        "$name": "description",
        "$options": {}
      }
    ]
  },
  "$name": "userForm",
  "$dirty": false,
  "$pristine": true,
  "$valid": false,
  "$invalid": true,
  "$submitted": false,
  "username": {
    "$validators": {},
    "$asyncValidators": {},
    "$parsers": [],
    "$formatters": [
      null
    ],
    "$viewChangeListeners": [],
    "$untouched": true,
    "$touched": false,
    "$pristine": true,
    "$dirty": false,
    "$valid": false,
    "$invalid": true,
    "$error": {
      "required": true
    },
    "$name": "username",
    "$options": {}
  },
  "description": {
    "$validators": {},
    "$asyncValidators": {},
    "$parsers": [],
    "$formatters": [
      null
    ],
    "$viewChangeListeners": [],
    "$untouched": true,
    "$touched": false,
    "$pristine": true,
    "$dirty": false,
    "$valid": false,
    "$invalid": true,
    "$error": {
      "required": true
    },
    "$name": "description",
    "$options": {}
  }
}

The description field is marked as required with 1.7.6 and not required with 1.7.5.

Expected / new behavior:

The code works the same on 1.7.5 and 1.7.6.

Minimal reproduction of the problem with instructions:

If really needed I can provide some example, but maybe you guys can find the cause without it.

AngularJS version: 1.7.6, snapshot too

Browser: [all | Chrome XX | Firefox XX | Edge XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView | Opera XX ]

Firefox 65

Anything else:

[jniles]

By any chance, are any of these in a ngRepeat or ngIf? If so, it is probably a manifestation of #16814.

[PalmerEldritch123]

Yup, this is a dynamic form which is generated by ng-repeat.
I was looking at open issues and didn't find anything related.
So probably this is duplicate and can be closed.

[gkalpak]

If that is the case, the code should work with the current snapshot. @PalmerEldritch123, can you verify that?

[PalmerEldritch123]

It's OK with current snapshot, I probably messed something up when I was testing it. Sorry for confusion :)

[gkalpak]

Awesome! Thx for following up.
