How can I get clang-format to put the parameters of a brace-initialized construction on the same line?

I'm running clang-format, with a .clang-format file which only specifies Language: Cpp, on this input (invalid C++, but that's unimportant for this):

const auto SOME_VARIABLE_NAME = {{"key", { {"key2", std::array{ 0, 0, 0, 0, }}, }}};

I get this output:

const auto SOME_VARIABLE_NAME = {{"key",
                                  {
                                      {"key2",
                                       std::array{
                                           0,
                                           0,
                                           0,
                                           0,
                                       }},
                                  }}};

I would something closer to the following output:

const auto SOME_VARIABLE_NAME = {{"key",
                                  {
                                      {"key2",
                                       std::array{0, 0, 0, 0}},
                                  }}};

I am not sure why clang-format puts a line break after each 0, around column 50.

What setting should I add to my .clang-format to achieve this?

I've tried a few specifiers that I thought might be relevant, to no avail:

• AllowAllParametersOfDeclarationOnNextLine: true
• AllowShortFunctionsOnASingleLine: true
• BinPackParameters: true
• BreakBeforeBinaryOperators: false
• ColumnLimit: 120
• ConstructorInitializerAllOnOneLineOrOnePerLine: true
• Cpp11BracedListStyle: false
• IndentFunctionDeclarationAfterType: true
• PenaltyBreakBeforeFirstCallParameter: 1000
• Standard: Cpp11

Edit: Still have this problem. Added a comment after the first brace to at least force the braces to the left more:

const auto SOME_VARIABLE_NAME = {  //
    {"key",
     {
         {"key2",
          std::array{
              0,
              0,
              0,
              0,
          }},
     }}};
