ChromeAppsWebViewPermissiveBehaviorAllowed

Chrome Apps <webview> allows for behavior which is in the process of being removed from Google Chrome. The previous behavior allows the <webview> newwindow event (https://developer.chrome.com/docs/extensions/reference/webviewTag/#event-newwindow) to attach the new window to a <webview> element in a separate App window from the originating <webview>. With the new behavior, this attachment is still allowed, however the window reference returned from the call to window.open in the originating <webview> is invalidated. If enabled, the previous behavior is used. If disabled or unset, the behavior change takes effect as it is rolled out through the Google Chrome release process. This policy is a temporary workaround in the event that enterprises experience breakage due to this change. The last supported version of this policy was version 121. It was removed in version 122.
