title: VSCode Autocomplete matching suggested case
body: <p>Autocomplete in Visual Studio doesn't match the suggested variable case.
  Example: I've got a variable "$arrayTest". When I start writing the variable name, visual studio rightly suggests the complete variable, but it completes it without checking the case of what I wrote to that point. So in this situation, if I write "$arrayt" and autocomplete, VS will maintain "$arraytest" instead of "$arrayTest", which is a real pain. Is there any way to adjust this setting?</p>
