//! Port of `StyledElementExtensions.cs`: the extension methods are members
//! of [`StyledElement`], the type they extend.
//!
//! The internal `IsClassesBindingProperty` is not repeated here: the one
//! caller in the framework (the setter) asks
//! [`ClassBindingManager::is_classes_binding_property`] directly.
