To Reproduce

1. Add an "after member" comment to a member of a struct, enum, prototype parameter, #define, etc. using any of these options for the syntax:
   • /**< ... */
   • /*!< ... */
   • ///<
   • //!<

For example:

#define SCIGCR1_CONT 0x20000 //!< @brief SCI Continue on suspend

typedef enum
{
    ECAP_FREE_SOFT_STOP         = 0x0000U, ///< @brief counter stops immediately on emulation suspend
    ECAP_FREE_SOFT_STOP_AT_ZERO = 0x4000U, /**< @brief counter runs until value equals 0 */
    ECAP_FREE_SOFT_RUN          = 0xc000U, /*!< @brief counter is unaffected by emulation suspend */
} ecap_free_soft_t;

struct line_hz_tick_range {
    double hz; ///< @brief nominal line frequency
    uint32_t ticks; //!< @brief eCAP1 ticks in period of nominal frequency
    uint32_t ticks_min; ///< @brief eCAP1 ticks in period of longest matching period
    uint32_t ticks_max; ///< @brief eCAP1 ticks in period of shortest matching period
};

Expected

• @brief and other Doxygen keywords should be highlighted as storage.type.class.doxygen.c
• Other comment text should be highlighted as comment.block.documentation.c or comment.line.double-slash.documentation.c

Actual

Entire comment is highlighted as comment.block.c or comment.line.double-slash.c
