发生了什么？
在我看来，这像是个bug。当注解由同一个字段管理器进行管理时，包括注解更改的服务器端PATCH操作会将更改合并，而不是完全替换注解。

你期望会发生什么？
当注解在服务器端由与引入它们的字段管理器相同的字段管理器进行PATCH操作时，希望注解被替换。如果行为是正确的，那么用服务器端 PATCH来替换整个Map的机制是什么？

我们如何尽可能最小精确地重现它？
需要提供的测试用例

我们需要了解其他信息吗？
这是对话捕获：
在下面的示例中，有一个带有注解的命名空间。命名空间通过带有注解 "a: x" 添加，PATCH操作应该用 "b: y" (相同的字段管理器)替换它们。然而，它们被合并了："annotations":{"a":"x","b":"y"}。
