title: iOS iPhone 11 flashing black and white while browsler is constantly reloading: RBS Background assertion ConnectionTerminationWatchdog
body: <p>I get a black &amp; white flashing browser, which is constantly reloading after this error:</p>
  <pre><code>[ProcessSuspension] 0x1063b4740 - ProcessAssertion: Failed to acquire RBS Background assertion 'ConnectionTerminationWatchdog' for process because PID is invalid
  [Process] 0x104028a18 - [pageProxyID=11, webPageID=12, PID=3734] WebPageProxy::processDidTerminate: (pid 3734), reason 3
  [assertion] Error acquiring assertion: &lt;Error Domain=RBSAssertionErrorDomain Code=3 &quot;Target is not running or required target entitlement is missing&quot; UserInfo={RBSAssertionAttribute=&lt;RBSDomainAttribute| domain:&quot;com.apple.webkit&quot; name:&quot;Background&quot; sourceEnvironment:&quot;(null)&quot;&gt;, NSLocalizedFailureReason=Target is not running or required target entitlement is missing}&gt;
  </code></pre>
  <p>The issue occurs only with iPhone 11 PRO and iPhone 11 Mini (real devices) and a cordova app on iOS 14.3, 14.4 and 14.5.
  On emulator it works perfectly and on other real devices as well.</p>
  <p>In my case the screen is flashing black and white if I open a dc-Tableview.js table (by adding and removing &quot;diplay:none&quot;).</p>
