Ionic doctor reporting "add viewport-fix=cover", but already there

#1

When I run ionic doctor check the following warning is reported:

:heavy_check_mark: Detecting issues: 15 / 15 complete - done!
[WARN] viewport-fit=cover not set in index.html

   iOS 11 introduces new "safe regions" for webviews, which can throw off component sizing, squish the header into 
   the status bar, letterbox the app on iPhone X, etc. Fixing this issue will ensure the webview takes up the full 
   size of the screen. See https://blog.ionicframework.com/ios-11-checklist for more information.
   
   To fix, take the following step(s):
   
     1) Add viewport-fit=cover to the <meta name="viewport"> tag in your index.html file
   
   $ ionic config set -g doctor.issues.viewport-fit-not-set.ignored true (ignore this issue in the future)

[INFO] Doctor Summary

   - Detected 1 issue.
   - 0 issues can be fixed automatically

But my index.html already has the line in it:

<!DOCTYPE html>
<html lang="en" dir="ltr">

    <meta charset="UTF-8">
    <title>Ionic App</title>
