Steps to Reproduce:

1. Create a new typescript project (I have used a nrwl nx workspace)
2. Add a new path to the paths object in the tsconfig to map a path to a folder (I created a new nx library) and make sure the path alias is nested (see my video)
3. Try to import from the path, start with typing 2/3 of the path and then press tab to autocomplete

Thanks @StefanKoenen!

Here's the completion entry that TS returns in this case:

[Trace  - 20:18:07.884] <semantic> Response received: completionInfo (113). Request took 2 ms. Success: true 
Result: {
    "isGlobalCompletion": false,

        },

                "kind": "text"
            }
        ]
    }
]

Note that there is no replacement range set in these cases so we always insert the full text at the current cursor position
