This is an issue with the assertion. We just need to disable it in WebKit1 like this in ScriptDisallowedScope.h:

        static bool isScriptAllowed()
        {
            ASSERT(isMainThread());
            if ()
#if PLATFORM(IOS_FAMILY)
            return isInWebProcess() || !s_count || webThreadDelegateMessageScopeCount;
#else
            return isInWebProcess() || !s_count;
#endif
        }

We can then isEventDispatchAllowedInSubtree like this:
        static bool isEventDispatchAllowedInSubtree(Node& node)
        {
#if ASSERT_ENABLED || ENABLE(SECURITY_ASSERTIONS)
            return isScriptAllowed() || EventAllowedScope::isAllowedNode(node);
#else
            UNUSED_PARAM(node);
            return true;
#endif
        }

@Rniwa - should I do PR with proposed changes?

Yes, please. I can do it too but I have other test failures to investigate at the moment.

No worries, will do in next few hours. 👍

Locally confirmed that it does indeed not crash while running:

run-webkit-tests --debug --iterations=1 -1  editing/inserting/break-out-of-nested-lists.html

and yes, I removed test expectation before running the above. :-)
