Screenshot of generated doc showing truncation

When a macro with arguments is used as part of a trailing attribute of a function, typedef and other elements, Doxygen seems to be truncating the argument list.

Given the source:

#define LIBINPUT_ATTRIBUTE_PRINTF(_format, _args) \
        __attribute__ ((format (printf, _format, _args)))

// ...
typedef void (*libinput_log_handler)(struct libinput *libinput,
                                     enum libinput_log_priority priority,
                                     const char *format, va_list args)
           LIBINPUT_ATTRIBUTE_PRINTF(3, 0);

The html doc for the typedef shows everything up to the comma in the used macro, like:

LIBINPUT_ATTRIBUTE_PRINTF(3
