[clang-format] Weird line breaks with `AlignAfterOpenBracket: BlockIndent`

[lukasberbuer]

Following example showcases weird line-breaking choices with AlignAfterOpenBracket: BlockIndent:

• Pure LLVM style:

  auto result = std::optional<int>(123)
                .transform([](int n) { return n + 100; })
                .transform([](int n) {
                    // multiline lambda
                    return std::to_string(n);
                });

• With AlignAfterOpenBracket: BlockIndent 💥:

  auto result = std::optional<int>(123).transform([](int n) { return n + 100; }
  ).transform([](int n) {
    // multiline lambda
    return std::to_string(n);
  });

• Desired output:

  auto result = std::optional<int>(123)
    .transform([](int n) { return n + 100; })
    .transform([](int n) {
        // multiline lambda
        return std::to_string(n);
    });

Any ideas how to fix this? Can it be done just via the config?
