Research direction

Read the SelectOptions definition and the menu_max_h builder, then trace how drop-up menus size and filter their options. Add the minimum-height option and builder described in the issue; done when setting menu_min_h and menu_max_h to the same value keeps the menu height stable while filtering in the settings window.

Description

搜索型 Select 在 drop-up 场景下，过滤把 20 项缩到 2 项时整个菜单会位移，鼠标目标在点击前跑掉。我们在 SelectOptions 中新增了 menu_min_h: Option 与 menu_min_h(Length) builder，与 menu_max_h 取同值时弹层高度恒定、只原地过滤，已验证可在设置窗口使用。
