Indents in C++ variable initialization with curly braces

Dear JB Community,

I want to initialize an std::vector in the following way:
std::vector<T> myVector {
  t1,
  t2,
  t3
};

where I want to have indents consisting of 2 spaces before t1, t2, t3. However I always get 4 there (I switched two 2 spaces all the C++ settings of indents but it does not help).
Does anybody know how to deal with it?
