Styles from Resources are not Cascading to when Style is also set in Xaml file

[jacobglanz]

Description

For example When setting a style trough the resource dictionary tag on a xaml page for all buttons even if you set CanCascade=True it won't work, and only the styles applied in this file will work and you'll lose all outside styling.

Steps to Reproduce

1. This problem is only with .Net8, not with .Net7, so make sure to use .Net8
2. Make a Maui Project
3. Make a Xaml page
4. Add a Button
5. Go outside of this file (to the Recourses>Styles) and make a style to target buttons and set the background blue, and make sure it works
6. Go back to your Xaml file make a style and target buttons (ContentPage.Resources>ResourceDictionary>Style tag) and set the border to red and set CanCascade=True, so the background color should still be blue
7. Now you'll find that in the case where you Set Styles in the xaml file it self, it will never take styles from above it, CanCascade will always be false, CanCascade=True does not work
