Change `EventHandler::handle_keydown()` to no longer assume the cursor position's node is always a `DOM::Text`. While this assumption holds for `HTMLInputElement` that has a shadow DOM with a text node, an empty `contenteditable` might not have any children. With this change, `handle_keydown()` creates a new text node if the cursor position's node is not a text node.
