Canvas Height Not Updating When ItemsSource Changes

[Gummimundur]

When binding to an ItemsSource, the content renders correctly initially. However, if the ItemsSource is updated, the height of the Canvas does not adjust to reflect the new content.

Hey thanks for reporting this, especially for repro! On it.

Thanks for the PR, a new version is going to be out this weekend, stable skiasharp v3 for net9. With hardware acceleration for windows, a game changer for creating MAUI desktop apps. :)
