From microsoft/vscode#268520

Repo

1. Staged a .ts file in VS Code using the scm view
2. In the scm view, click on the staged file to open it in an editor
3. Try using go to symbol or go to definition in the editor

Bug
Nothing happens

We should be able to enable syntax only features in these files, such the document outline (go to symbol)

Would be great to support go to definition too
