Regression in GoToAsync behavior on Windows in 9.0.12

[jeremy-visionaid]

Description

When using an MMVM RelayCommand to invoke GoToAsync, the button invoking the command becomes disabled on Windows.

The behavior is as expected on iOS and Android, and on MAUI 9.0.10 on Windows.

Steps to Reproduce

Clone the repro repo (gotoasync branch)

1. Click the "Click me" button
2. Click the back button

The "Click me" button is now disabled

Oh, the button can actually still be clicked! It's just the style that is off... i.e. it just looks disabled

@jeremy-visionaid I tested your sample on 9.0.0, 9.0.10 and 9.0.12

I'm seeing the same behavior on both versions where the button visually disables

[jeremy-visionaid]

After clicking the "Click me" button... then "Back"

9.0.10:

9.0.12:

🤷

@PureWeen Did you do a clean/rebuild? I don't think it shows up on an incremental build just changing the version number (which is another problem...).

What version of windows are you on?

[jeremy-visionaid]

24H2: Version 10.0.26100 Build 26100

I'll see if I can repro on a different machine...

Same

@PureWeen I can repro on both my desktop (Ryzen + NVidia) and my laptop (Intel GPU/GPU), both 24H2.

I assume you can also click the button even though it appears disabled? What happens on Android/iOS for you? For me the button appears enabled on every combination except 9.0.12 on Windows.

Looks like reverting #26108 restores the behaviour in 9.0.10, but I'll just double check...

yea, the behavior is consistent for me between all net9 versions

click button
goes to next page
click back arrow
button looks disabled
button still works

I pinged some folks to test once they are around in a few hours as well

This issue has been verified using Visual Studio 17.13.0 Preview 2.1 (9.0.12). Can repro this issue on Windows Platform, and "Click Me" button works fine on Android platform. And 9.0.10 works fine.

@PureWeen Just to confirm, this is working again in 9.0.14 after reverting #26108
