 * into the inline toolbar AND does not manage its own line breaks. Tools that
 * manage line breaks own the full keyboard inside their content, so a trigger
 * character must stay literal there.
 *
 * When no tool can be resolved the block is treated as text-like so the
 * regular paragraph/header menus are never blocked.
 * @param tool - the current block's tool, or undefined when no block is resolved
