Lower to Pri-3 because real world usage of InsertUnorderList is low. The root cause is |VisiblePosition::FirstPositionInNode(OL)| returns null-Position in InsertListCommand::DoApplyForSingleParagraph() as an argument of |MoveParagraphWithClone()|. DOM tree is: BODY (editable) (focused) UL (editable) LI (editable) #text "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" DIV class="CLASS12" #text "\nAxBxC\n" #text "\n" UL (editable) * OL class="CLASS3" (editable) #text "\n" FORM class="CLASS4 CLASS12" #text "\n" #text "\nAxBxC b"
