Fix T79234: Material preview does not update

When changing the material while the properties editor temporarily isn't
visible (e.g. because another editor is in full-screen or a different
workspace is active), the preview wouldn't be updated on changes.

Always trigger a material preview update on screen layout or editor type
changes.
