Hot Reload does not work or stops working in some specific cases

[jsuarezruiz]

Description

I have noticed that updating VisualStates from a style https://github.com/jsuarezruiz/netmaui-movies-app-challenge/blob/main/src/MoviesApp/Views/MoviesView.xaml#L19, especially complex elements such as CarouselView or Border, stops XAML Hot Reload from working.

Updating VisualStates (without styles) does not update the changes. https://github.com/jsuarezruiz/netmaui-movies-app-challenge/blob/main/src/MoviesApp/Views/MoviesView.xaml#L146

Steps to Reproduce

1. Download or sync https://github.com/jsuarezruiz/netmaui-movies-app-challenge
2. Launch the App on an Android emulator.
3. Try to update the shared lines from VisualStates.

This is probably related to the huge overhaul of the property setter specificity work as part of https://github.com/dotnet/maui/issues/11082

This issue should not be closed. tag partner/hot-reload-xaml is accurate as an item to be track in the MAUI debot

I am testing on the current net7.0 maui with the current VSMac.

Changes within the VisualState itself are not reflected. As far as I can see, we're not sending any XAML Actions for these changes, so the app doesn't have a chance to update it.

So if you change the individual value of the setter (Like the text color) nothing is sent to the application. If you change the entire list (As in, replace the entire VisualState or the VisualStateGroup) then it sends actions to replace the whole thing and then it reloads.

Having the style attached at all to a control shouldn't matter.

Assigning myself to this for the moment so it's tracked, most likely this will be a XET issue but having this around is fine for visibility.

Not sure how to reproduce exactly, but modifying content from a ContentView used as CollectionView ItemTemplate

@jsuarezruiz I can't reproduce that on Android nor WinUI. I was able to make changes on the underlying ContentView and it showed fine. Was that on iOS? Do you have Logs?
