Jacob Weber created CB-13956:
--------------------------------

             Summary: InAppBrowser safe-area-inset margins wrong on iPhone X
                 Key: CB-13956
                 URL: https://issues.apache.org/jira/browse/CB-13956
             Project: Apache Cordova
          Issue Type: Bug
          Components: cordova-ios, cordova-plugin-inappbrowser
    Affects Versions: cordova-ios 4.5.0
         Environment: Mac OS 10.13.3, cordova-cli 8.0.0, node 8.9.4
            Reporter: Jacob Weber
            Assignee: Suraj Pindoria
         Attachments: 1. portrait.png, 2. landscape.png, 3. portrait.png, CordovaTest.zip

The in-app browser doesn't use the correct margins on an iPhone X, if you try to use {{viewport-fit=cover}} along with the {{safe-area-inset-*}} constants.

To reproduce:
{code:java}
cordova create CordovaTest com.sample.cordovatest CordovaTest
cd CordovaTest
cordova platform add ios@4.5.4
cordova plugin add cordova-plugin-inappbrowser
cordova plugin add cordova-plugin-statusbar{code}
Then to make it work on the iPhone X, create a 2732x2732 image and add it to config.xml:
{code:java}
<splash src="res/screen/ios/Default@2x~universal~anyany.png" />{code}
and add {{viewport-fit=cover}} to the {{viewport}} tag of {{www/index.html}}.

Finally, create an HTML page to load in the in-app browser, and store it on some web server:
{code:java}
<html>
<head>
  <meta name="viewport" content="initial-scale=1, width=device-width, height=device-height, viewport-fit=cover" />
<style>
html {
  background-color: #00FFFF;
}
body {
  border: 1px solid red;
  margin-top: env(safe-area-inset-top);
  margin-bottom: env(safe-area-inset-bottom);
  margin-left: env(safe-area-inset-left);
  margin-right: env(safe-area-inset-right);
}
</style>
</head>

<body>
</body>
</html>
{code}
Now launch this on an iPhone X simulator running iOS 11.2, attach a Safari debugger, and open the page in an in-app browser, e.g. {{window.open("https://myserver.com/test.html", "_blank");}}

The attachments show what you'll see.
 # Starting in portrait, the borders look correct.
 # Rotate to landscape, and the left/right safe-area margins aren't applied.
 # Rotate back to portrait, and now things are different. The left/right sides have safe-area margins when they shouldn't, and the top doesn't have one when it should.

If you load the same page directly in Safari, it behaves as expected.
