clang-format 14 wrongly indents `while [[unlikely]]`

clang-format 14 wrongly indents bodies of while loops which are annotated with [[unlikely]]

Here is a diff of how clang-format would reformat one of my functions:

 static inline void trimTrailingZeros(const char* begin, const char*& limit) {
    while ((begin != limit) && (limit[-1] == '0')) [[unlikely]] {
-      --limit;
-   }
+         --limit;
+      }
 }

Formatting your example using either 14.0.3 or main, I got:

static inline void trimTrailingZeros(const char *begin, const char *&limit) {
  while ((begin != limit) && (limit[-1] == '0'))
    [[unlikely]] { --limit; }
}

The expected output should be:

static inline void trimTrailingZeros(const char *begin, const char *&limit) {
  while ((begin != limit) && (limit[-1] == '0')) [[unlikely]] {
    --limit;
  }
}
