Bug report

• Protractor Version: 6.0.0

element.isPresent() by protractor 6.0.0 returns false in case an element is disabled.
should return true even if the element is disabled

5.4 version:
https://github.com/angular/protractor/blob/release-5.4/lib/element.ts#L1094

return arr[0].isEnabled().then(() => {
  return true;  // is present, whether it is enabled or not
}

Current master and protractor 6.0.0 version:
https://github.com/angular/protractor/blob/master/lib/element.ts#L1057

// is present, whether it is enabled or not
return await arr[0].isEnabled();

wrong modified by this commit:
c0917aa#diff-b9fb06f01b394eaf53b0ff0316aae56dR1074

Possible solution:

// Calling any method forces a staleness check
await arr[0].isEnabled();
return true;
