Why same code, works differently between clang-18 and clang(trunk)?

Example: https://godbolt.org/z/PrfTj8voW

Sample of code:

struct Sample {
    nlohmann::json obj{nlohmann::json::object()};
};

On clang-18: obj property is set as object; - {}
On clang(trunk) and gcc: obj property is set as array of objects; - [{}]
