Screenshot of the example

If an if statement includes an init-statement, itself and the conditional will be not highlighted fully. In addition a variable declared in the init statement will not have a semantic colored assigned to it. 
This is with C++17 selected in the project configuration.
Example:

    if (auto b = std::vector<int>().size(); b > 2) {
        b = 5;
        auto c = std::vector<int>().size();
    }
