The ' before the a is intentional, thats how we display anonymous type names in VS as well. The coloring is coming from the C# textmate grammar. I believe it thinks the ' is an unclosed string, hence the red coloring on the a and the } in your second example.

We unfortunately don't have a lot of control over the colorization here - we mark code blocks and it colors. However we may be able to make some adjustments (potentially removing the ' for VSCode) to try and get a little better colorization.
