Description

Strange Picker behaviour when used in NavigationPage, After multiple calls to PushAsync,The IsEnable property of the Picker does not work,

1. The Picker project selector automatically opens, even if it is disabled.
2. A Picker item is selectable, even when IsEnabled is set to False.

This issue has been present since MAUI7 and has been replicated on the latest MAUI8-RC2.
This issue was reported on #2349 and inexplicably closed.

Steps to Reproduce

在Android7.1下运行

1. 点击 名称为"Navigate new page"的按钮
2. 在新的界面再次点击"Navigate new page"按钮
3. 点击返回的小箭头,界面回退后,Picker竟然自动展开了. 但是此时Picker无法通过点击选择子项
4. 再次后退,Picker虽然不会自动展开 但是IsEnable属性失效了,竟然可以点击选择.当选择完成后,再次点击IsEnable属性又再次生效,无法点击

Running under Android 7.1

1. Click on the button named "Navigate new page"
2. Click on the "Navigate new page" button again in the new interface
3. Click on the small arrow to return, and after the interface recedes, the Picker unexpectedly expands automatically But at this point, Picker cannot select sub items by clicking
4. Step back again. Although the Picker will not automatically expand, the IsEnable attribute is False and can be clicked to select. After the selection is completed, The IsEnable attribute takes effect and cannot be clicked

Ive observed similar behavior on Android, where it appears a random Picker has been forced to focus and activate in the same manner as show in this bug report.
This may happen as when a keyboard return is invoked, it can force focus to another control as stated.
Or as in this case a Page is navigated to and focus is given/forced to the first/only control, and activated if it happens to be a Picker

Im not yet aware how to control this focus/activate behavior.

Any workaround on that one?
