Using ///<LF> (aka C++ DoxyGen comments) without any trailing characters confuse syntax highlighter, causing all highlight to be shifted one line down, per single line.

Try opening attached .h file. Or type in the newly opened C++ header editor:

/// 1
///
/// 2
///
/// 2
///
/// 3

template <typename PixelType,
          typename LORType,
          typename SType = int,
          typename HitType = int>
class MatrixPixelMajor {
 public:
  typedef PixelType Pixel;
  typedef LORType LOR;
  typedef SType S;
  typedef HitType Hit;
};

This problem doesn't affect previous Beta, so it was introduced somewhere in after Beta, and only affects RC.
