listContext 造成useWatch 失效

正常运行的版本：

失效的版本

貌似是这个pr改动造成的：https://github.com/react-component/field-form/pull/582

看了源码，是由于ListContext 这个全局变量造成 isListField 被错误打标为true，造成：

// useForm.ts  getFieldsValue方法
if (!nameList && (entity as FieldEntity).isListField?.()) {
  return;
}

引起错误的代码为这里

  //  这里初始化时， 正常时拿到的是 null, 但那个错误包版本拿到的是 { f(getKeys) }
  const wrapperListContext = React.useContext(ListContext);

  const listContext = React.useMemo<ListContextProps>(
    () => ({
      getKey: (namePath: InternalNamePath) => {
        const len = prefixName.length;
        const pathName = namePath[len];
        return [keyManager.keys[pathName], namePath.slice(len + 1)];
      },
    }),
    [prefixName],
  );


    <ListContext.Provider value={listContext}>
      <FieldContext.Provider value={fieldContext}>
        <Field
          name={[]}
          shouldUpdate={shouldUpdate}
          rules={rules}
          validateTrigger={validateTrigger}
          initialValue={initialValue}
          isList
          isListField={isListField ?? !!wrapperListContext}
        >
<.....>

出错的场景就是 Form 嵌套，但formList 并没有嵌套，但共用了同一个 ListContext 伪代码如下

// ModalAdapter.tsx
export function ModalAdapter(props: {
  value?: any;
  onChange?: (value: any) => void;
}) {
    const [form] = Form.useForm();
     return (
     <Modal>
      <Form form={form}>
        <Form.Item lable="属性a">
          <Form.List name="attra">
            ....
          </Form.List>
        </Form.Item>
        <Form.Item lable="属性b">
          <Form.List name="attrb">
            ....
          </Form.List>
        </Form.Item>
      </Form>
     </Modal>);
}

// index.tsx

                  <Form.Item label="测试列表">
                    <Form.List
                      name="testList"
                    >
                      {(fields, { add, remove }) => (
                        <>
                          {fields.map(field => {
                            return (
                            <div key={field.key} className="setting-list-item">
                              {fields.length > 1 ? <CloseCircleFilled
                                style={{ color: '#CCCCCC' }}
                                onClick={() => {
                                  remove(field.name);
                                }}
                              /> : null}
                              <Form.Item
                                noStyle
                                name={[field.name, 'attr']}
                              >
                                <ModalAdapter  />
                              </Form.Item>
                            </div>
                          )
                          })}
                          {fields.length < 10 && <Form.Item>
                            <div onClick={add} className="setting-list-operate">
                              <PlusCircleFilled />
                                  添加属性
                              <span>({fields.length}/10)</span>
                            </div>
                          </Form.Item>}
                        </>
                      )}
                    </Form.List>

Start with the ListContext handling and getFieldsValue condition shown from useForm.ts, then compare the suspected changes in pull request 582. Reproduce the nested Form and separate Form.List scenario using ModalAdapter.tsx and index.tsx, and verify that useWatch works when the surrounding form does not contain a nested Form.List.
