InAppBrowser safe-area-inset margins wrong on iPhone X



    • Bug
    • Status: Open
    • Major
    • Resolution: Unresolved
    • cordova-ios 4.5.0
    • None
    • None
    • Mac OS 10.13.3, cordova-cli 8.0.0, node 8.9.4


      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:

      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

      Then to make it work on the iPhone X, create a 2732x2732 image and add it to config.xml:

      <splash src="res/screen/ios/Default@2x~universal~anyany.png" />

      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 as www/sample.html:

        <meta name="viewport" content="initial-scale=1, width=device-width, height=device-height, viewport-fit=cover" />
      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);

      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("sample.html", "_blank");

      (In the attached app, you can just tap the Cordova icon to open it.)

      The attachments show what you'll see.

      1. Starting in portrait, the borders look correct.
      2. Rotate to landscape, and the left/right safe-area margins aren't applied.
      3. 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.

      The gray status-bar overlay gets in the way of seeing exactly what's happening; see CB-13583.
