🧐[问题]请问，proFormList，max设置1，然后使用自定义按钮添加，自带的按钮超过1一条之后，还是会自动显示出来呢

proFormList内部自定义了一个添加按钮，如何在点击自带的添加按钮之后，隐藏自带的呢。尝试使用max属性，添加一条之后会隐藏，但是在使用自定义添加，自带的添加按钮又会显示出来

Start with the linked CodeSandbox's App.tsx and reproduce the ProFormList case using max=1, a custom add button, and the built-in add button. Trace how the list limit and button visibility respond to custom additions; done means the built-in button stays hidden after one item is added.
