Getting function arguments to align automatically when hitting enter

Type: LanguageService

Describe the bug

• OS and Version: Mac OS Mojave 10.14.6
• VS Code Version: 1.46.1
• C/C++ Extension Version: 0.28.3
• Other extensions you installed (and if the issue persists after disabling them):
  • All Autocomplete
  • Microsoft C/C++ official
  • Better C++ Syntax
  • Hungry Delete

The issue persists even when running code --disable-extensions

Supposed I have code like this:

    myFunction(arg1, arg2, arg3);

In Sublime Text, when I put the cursor in front of the arg2 and hit enter, the rest of the function call moves down a line and arg2 lines up with arg1 like so:

    myFunction(arg1, 
               arg2, arg3);

However, if I do the same in VS Code, the arg2 lines up to the current indentation level:

    myFunction(arg1, 
    arg2, arg3);

I can repeatedly hit the tab key to move it over 4 spaces at a time, but since the start of arg1 is 11 spaces away, I either have to deal with a slight misalignment like so:

    myFunction(arg1, 
                arg2, arg3);

or I have to use the spacebar as well as the tab key to align it just right.

If I simply bring arg2 to the next level and use "Format Selection", I get everything to align perfectly. However, I was wondering if there's any way to get this behavior to occur automatically by hitting enter.

Note that I don't want "Format Document" to run automatically; I want to keep the rest of the file as is and just have things line up as I move them to new lines.

The issue names no file or test, but identifies the C++ LanguageService and the existing Format Selection behavior. Start by locating handling for Enter/newline indentation and compare it with formatting; done means function arguments align automatically on Enter without formatting the rest of the document.
