Syntax highlighting issue when null conditional accessor split with a newline

[AshleyWorkmanBoomi]

Issue Description

Syntax highlighting breaks when the null conditional access operator is split, first the wrong colours are used and then this progresses to a complete lack of colour. Enabling the csharp.semanticHighlighting.enabled option corrects the highlighting issue.

Steps to Reproduce

The following example reproduces this issue:

            var list = new List<string>()?
                            .Select(x => x).Distinct().ToArray();

            foreach(var element in list)
            {
                switch (element)
                {
                    case "Case One":
                        break;
                    default:
                        break;

                }
            }

            return list;

This was recently fixed in the C# textmate grammar (dotnet/csharp-tmLanguage#216). It should flow automatically flow into VS Code for the October release. You can set csharp.semanticHighlighting.enabled to true to enable our semantic highlighting which will also resolve this issues for you.
