It's expected that an input element has a shadow root and an editable div inside of it. What's rather unexpected is that the fragment in createFragmentFromText has an input element in it based on your second output. How are those input elements end up being placed there? 1732488 5 fred.wang 2021-02-23 04:35:54 -0800 (In reply to Ryosuke Niwa from comment #4) > That document fragment is probably a shadow root.

How are those input > elements end up being placed there? So as I mentioned in comment 3, this is generally very similar to bug 221387, where a "bad" enclosing block is selected, cloned for each line break by createFragmentFromText and causes issues later in the code. A patch to force useClonesOfEnclosingBlock to false allows to work around the issue here too, but we probably want a more general approach (I haven't investigated yet why the <input> tag is causing issues later in the code). In this particular case, the start context is the <meta> tag, to which the test appends an <input> child. Additionally, the test forces `display: block;` on that input tag, so it is selected as the enclosing block. See more debug output below. https://webkit-search.igalia.com/webkit/rev/5040394ad2b060de17f12aa8f84018147f22b4f4/Source/WebCore/editing/markup.cpp#1203 (rr) p showTree(start.firstNode().get()) #document 0x7fa43f156c70 (renderer 0x7fa43f155250) HTML 0x7fa43f157a80 (renderer 0x7fa43f1556c0) HEAD 0x7fa43f157b10 (renderer 0x7fa43f148350) META 0x7fa43f157ba0 (renderer 0x7fa43f148470) * INPUT 0x7fa43f1480a0 (renderer 0x7fa43f148590) #document-fragment 0x7fa43f1481b0 (renderer (nil)) (needs style recalc) (child needs style recalc) DIV 0x7fa43f1482c0 (renderer 0x7fa43f1486b0) #text 0x7fa43f157c30 "\n" STYLE 0x7fa43f157ca0 (renderer (nil)) #text 0x7fa43f157d60 "\n" #text 0x7fa43f157dd0 "\n" SCRIPT 0x7fa43f157e40 (renderer 0x7fa43f1487d0) #text 0x7fa43f157f10 "\n onload = () => {\n document.styleSheets[0].insertRule(`head, script, meta, input { display: block; }`);\n document.styleSheets[0].insertRule(`input { text-indent: 1px; }`);\n document.querySelector('meta').appendChild(document.createElement('input'));\n document.execCommand('SelectAll');\n document.designMode = 'on';\n document.execCommand('Copy');\n document.execCommand('PasteAsPlainText');\n };\n" #text 0x7fa43f157f80 "\n" BODY 0x7fa43f148010 (renderer 0x7fa43f1557e0) $1 = void (rr) p start.firstNode().get()==block $2 = true 1732519 6 fred.wang 2021-02-23 07:20:00 -0800 (In reply to Frédéric Wang (:fredw) from comment #5) > (I haven't investigated yet why the <input> tag is causing issues later in the code). So here is what's happening. The <input> tag is initially a child of <body> when WebCore::ReplaceSelectionCommand::doApply() calculates m_startOfInsertedContent. But at the end of that method, the call to ReplaceSelectionCommand::completeHTMLReplacement() ends up executing moveParagraphContentsToNewBlockIfNecessary() which wraps copies of the <input> elements into a new <div> tag. The original <input> elements are detached from the tree. When we later try to access the container node of m_startOfInsertedContent, we obtain a null pointer, causing a nullptr dereference.
