RootInlineBox->prevLineBox() and nextLineBox() only catches the multiple lines caused by wrapping or by <br> in <div>abc def<br>hij opq</div>.
For the <br> in <div>abc def <div><br></div>hij opq</div> (or the newline entered by user in contenteditable div), we need to find the previousRootInlineBox in order to go from "hij opq" to "abc def".
