Bug 1749299 - Make `HTMLEditor::HandleInsertLinefeed()` stop handling it if insertion point cannot have text nodes r=m_kato Ideally, it should not be called when the editor cannot insert new text node. However, the callers are complicated. Therefore, let's check in it for avoiding making the callers more complicated. Fortunately, this is not realistic path for normal web apps. Therefore, the compatibility of the behavior is not matter. That's the reason why this patch does not have a test comparing the result.
