1. Open vscode at typescript repository
2. Open file src/tsc/tsc.ts
3. Use goto Definition on say "normalizePath"
   With this vscode calls definitionAndBoundSpan which returns definition in src/compiler/utilities.ts so vscode closes src/tsc/tsc.ts and opens src/compiler/utilities.ts and navigates to utilities.ts
   tsserver deletes src/tsc/tsconfig.json project and creates src/compiler/tsconfig.json
   If navigated back, it will close src/compiler/utilities.ts and hence its project and reopen src/tsc/tsc.ts and creating that project again.

I think we want to keep configured project if projectReferences in tsconfig refers to configured project which has openRef
