Misleading error in pipeline after another pipeline is added to it

Given this code:

```fsharp
let evenSquaredAndPotented values potention =
values
|> List.filter (fun x -> x % 2 = 0)
|> List.map (fun i -> i ** 2)
|> List.map (fun i -> i + potention)
```

You see this result:

It reports line 3 as the source of the problem when it is actually at line 4.

The issue is actually at `i ** 2`.

If you remove `|> List.map (fun i -> i + potention)` line, the range is correctly showing `**`.

* F# script file
* VS 15.9.3
* Same behavior with F# 4.0 [link](https://repl.it/@cartermp/GlisteningBoilingQuagga)
