<pre>
    In our codebase, we use macros when exporting types for dlls.
This enables conditionally enabling exporting the type, as well as supporting different compilers (e.g. `__declspec(dllexport)` vs `__attribute__ ((dllexport))`).

In clang-format 18.1.6 this formats as expected.
E.g. using the default style:
```cpp
struct EXPORT StructName {};

class EXPORT ClassName {
public:
  ClassName() {}
};
```

However, testing the latest version of clang-format 19 (f779ec7c13bdfccd29655d13a325f34c60797a76), the formatting has changed.
It appears that it is instead interpreting it as an initialization.
I.e.
```cpp
struct EXPORT StructName{};

class EXPORT ClassName{public : ClassName(){}};
```
