The test isn't even asynchronous. It is a pretty simple test that runs all its logic synchronously (no need for calling notifyDone).

[Chris Dumez]

It seems it isn't just this test. When this test times out on the iOS bot, about 50 other editing tests (e.g. editing/pasteboard/19644-1.html) also time out.

[Chris Dumez]

The tests seem to have the following logging on stderr which could be related:

objc[83889]: Class _PathPoint is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/UIKitCore.framework/UIKitCore (0x121604a78) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/TextInputUI.framework/TextInputUI (0x136f028b0). One of the two will be used. Which one is undefined.

One of the two will be used. Which one is undefined.

I think this is benign logging.

These mass editing failures are a different issue, caused by booted iOS simulators from a previous test run being used for a subsequent run, which means the "Automatically sync pasteboard" setting will be erroneously flipped on (which then causes `pasted` to deadlock when running tests in multiple sims).

It looks like this is one example of importNode-cdata.html timing out independently of the editing tests:

Ok, thanks for looking. The imported blink test also doesn't seem to rely on editing at all (no copy/paste like the other tests).
