Research direction
Reproduce the case described in the issue: an anonymous callback inside class A calls an A method, while A contains an instance of empty class B. Compare compilation with and without a property in B, then trace the compiler path producing static_assert(!std::is_empty{}); done means the valid empty-class case compiles without the assertion.

Description
Внутри класса A регистрирую коллбек в виде анонимной функции, в нём выполняется метод класса A. Одним из свойств класса A является экземпляр класса B, в классе B нет свойств. При компиляции выскакивает ошибка:
static_assert(!std::is_empty{}, "class T may not be empty")
Если добавить в класс B произвольное свойство, ошибка компиляции исчезает.
