// NOTE: Original ANGLE_instanced_arrays name is changed to title case,
// so it matches corresponding C++ class name, and does not require
// IDL generator to handle snake_case to TitleCase conversion.
// Having a different name is totally fine, because LegacyNoInterfaceObject
// prevents the name from being exposed to JavaScript.
