The problem is that the style referenced from InspectorStyle::m_style is stale, even though the Element in InspectorStyleSheetForInlineStyle::m_element field of its container is the same as the considered Element.


The prob

(gdb) f 1

(gdb) p *this->m_style
$50 = {<WebCore::StyleBase> = {<WTF::RefCounted<WebCore::StyleBase>> = {<WTF::RefCountedBase> = {m_refCount = 1131377775,
        m_deletionHasBegun = 97,
        m_adoptionIsRequired = 115}, <WTFNoncopyable::Noncopyable> = {<WTF::FastAllocBase> = {<No data fields>}, <No data fields>}, <No data fields>}, _vptr.StyleBase = 0x67207b2020202020, m_parent = 0x6f63203b3938203d}, <No data fields>}
