具体重现方法查看视频和代码，当我页面组件在消失并重现后，rightbuttom会消失，重复操作后又会出现，但设置了clearable为false时候不会出现

期望结果

页面重组后rightbutton属性里面的组件不会消失

实际结果

页面重组后rightbutton属性里面的组件会消失

补充说明

No response

Start at the TDInput implementation and its rightBtn and clearable handling, then reproduce the issue with the provided BookFormScreen and controller. Compare rebuilds with clearable enabled and disabled. Done means the right button remains visible after the page components are removed and rebuilt.
