From 7dddb19ca4bca9685adb734c76dcf72c3f610007 Mon Sep 17 00:00:00 2001 From: Michał Gołębiowski-Owczarek Date: Mon, 29 Apr 2019 19:54:12 +0200 Subject: Core: Make isAttached work with iOS 10.0-10.2 The test for Shadow DOM v1 support has been changed to rely on the presence of `documentElement.getRootNode` as iOS 10.0-10.2 supports `attachShadow` but doesn't support `getRootNode`. No new test is necessary - iOS 10.0 fails lots of our test suite because of this bug.
