I was not able to reproduce the failure locally o iOS 15 simulator using run-webkit-tests --force --ios-simulator --iterations 500 --exit-after-n-crashes-or-timeouts 1 imported/blink/fast/dom/importNode-cdata.html

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

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.

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. objc[83889]: Class _PointQueue 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 (0x121604a50) 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 (0x136f028d8). One of the two will be used. Which one is undefined.

I think this is benign logging. > When this test times out on the iOS bot, about 50 other editing tests (e.g. editing/pasteboard/19644-1.html) also time out 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: <https://build.webkit.org/#/builders/369/builds/492/steps/11/logs/stdio>

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