Button "Next" and "Complete" doesn't work if end-user has fixed an error in the the focused question

[andrewtelnov]

The minimum reproducable JSON:

{
 "pages": [
  {
   "name": "page1",
   "elements": [
    {
     "type": "text",
     "name": "q1",
     "isRequired": true
    }
   ]
  }
 ],
 "checkErrorsMode": "onValueChanged"
}

Press "Complete" with empty q1, then add a symbol into q1 question, without losing the focus from q1 press "Complete" button again. As result the error will be disappeared, but survey will not be completed. The focus will be on the "Complete" button. End-user will have to press one more time on "Complete" button.
