Snippets Are Not Rendering Anymore

The GIF above exemplifies the issue. Notice when it injects the code Bar(x: {{1:Int}}, y: {{2: String}}) that VSCode is not treating the arguments as tab stops.

It used to do this. This might have regressed Adopt SnippetString API. Though as far as I can tell we do this already.

My best guess right now is that the LSP defines a property insertTextFormat which is of type InsertTextFormat. Currently this implementation of the LSP has no such property or type. I do not remember that being there when I originally implemented this.

Still does not work. 🤔
