        <pre>With this simple code:
----
namespace mozilla {

#define IPV6_SCOPE_GLOBAL 0      // Global scope.
#define IPV6_SCOPE_LINKLOCAL 1   // Link-local scope.
#define IPV6_SCOPE_SITELOCAL 2   // Site-local scope (deprecated).
#define IPV6_SCOPE_UNIQUELOCAL 3 // Unique local
#define IPV6_SCOPE_NODELOCAL 4   // Loopback

} // namespace mozilla
----

clang-format-10 left it intact

With clang-format-11, the output is:
----
% clang-format-11 IPv6Utils.h
namespace mozilla {

#define IPV6_SCOPE_GLOBAL 0 // Global scope.
#define IPV6_SCOPE_LINKLOCAL 1 // Link-local scope.
#define IPV6_SCOPE_SITELOCAL 2 // Site-local scope (deprecated).
#define IPV6_SCOPE_UNIQUELOCAL 3 // Unique local
#define IPV6_SCOPE_NODELOCAL 4 // Loopback

} // namespace mozilla
----

which is a significant regression for clang-format-11
