Similar to https://bugs.webkit.org/show_bug.cgi?id=239353, there is a "use-after-free" warning in `WebCore/page/Navigation.cpp`: ``` In file included from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/text/CString.h:33, from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/text/StringView.h:34, from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/text/StringConcatenate.h:32, from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/text/AtomString.h:355, from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/text/StringHash.h:26, from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/JSONValues.h:36, from /home/vitaly/WebKit/Source/WebCore/platform/graphics/IntSize.h:30, from /home/vitaly/WebKit/Source/WebCore/platform/graphics/IntPoint.h:28, from /home/vitaly/WebKit/Source/WebCore/platform/animation/AnimationUtilities.h:29, from /home/vitaly/WebKit/Source/WebCore/platform/Length.h:25, from /home/vitaly/WebKit/Source/WebCore/platform/LengthFunctions.h:27, from /home/vitaly/WebKit/Source/WebCore/rendering/RenderElement.h:26, from /home/vitaly/WebKit/Source/WebCore/rendering/RenderLayerModelObject.h:26, from /home/vitaly/WebKit/Source/WebCore/page/LocalFrameViewLayoutContext.h:29, from /home/vitaly/WebKit/Source/WebCore/page/LocalFrameViewLayoutContext.cpp:27, from /home/vitaly/WebKit/WebKitBuild/GTK/Release/WebCore/DerivedSources/unified-sources/UnifiedSource-767013ce-6.cpp:1: In member function ‘bool WTF::RefCountedBase::derefAllowingPartiallyDestroyedBase() const’, inlined from ‘bool WTF::RefCountedBase::derefBase() const’ at /home/vitaly/WebKit/WebKitBuild/GTK/Release/WTF/Headers/wtf/RefCounted.h:155:51, inlined from ‘void WTF::RefCounted<T, Deleter>::deref() const [with T = WebCore::AbortController;
