Description
Describe the bug
在使用 HandyControl 的 hc:Window 作为主窗口时，窗口刚初始化时，点击最大化按钮会抛出 ElementNotEnabledException。
测试时还发现，即使设置 IsEnabled="False"，最大化按钮依然可以点击（最小化和关闭按钮会被禁用），但主要问题是初始化阶段最大化按钮可点且会报错。
Steps to reproduce the bug
- 在 XAML 中使用 hc:Window 作为主窗口
- 启动程序，在窗口刚显示时点击最大化按钮
- （附带问题）如果设置 IsEnabled="False"，最大化按钮依然可用，最小化和关闭按钮会被禁用。

Research direction
Start by reproducing the issue with an hc:Window main window in a .NET 8.0 WPF application, clicking maximize as the window appears and checking the IsEnabled="False" behavior. Trace the hc:Window initialization and title-bar button enabled-state handling; done means startup maximize no longer throws ElementNotEnabledException and disabling the window also disables maximize.
