Extended Description

Input:

  $ cat test.cc 
  template <template <typename> class A,
            template <typename> class B,
            typename C,
            typename D>
  struct TemplatedClass {};

Output for Mozilla style:

  $ clang-format --style=Mozilla test.cc
  template<template<typename> class A,
           template<typename>
           class B,
           typename C,
           typename D>
  struct TemplatedClass
  {};

Output for Chromium style:

  $ clang-format --style=Chromium test.cc
  template <template <typename> class A,
            template <typename>
            class B,
            typename C,
            typename D>
  struct TemplatedClass {};

One might have expected "template " and "class B" to be on the same line, as is the case with the first template template parameter.

As noted in #61732, the only deciding factor is BinPackParameters
