FSI in Visual Studio seemingly confuses line numbers

[inosik]

When code snippets are send to FSI from the editor, and then at the call site in the REPL there's a compilation error, FSI confuses line numbers and prints wrong lines as being incorrect. Looks to be related to #14717 (comment).

Repro steps

1. Create a new F# script file and add some code

   For example, this:

   let sum a b = a + b

2. Send the function to F# Interactive

3. Call the function in the F# Interactive window, but incorrectly

   For example, like this: sum 1 2 3

Expected behavior

The output should look like this (from VS 2019):

> val sum : a:int -> b:int -> int

> sum 1 2 3;;

  sum 1 2 3;;
  ^^^^^^^

stdin(3,1): error FS0003: This value is not a function and cannot be applied.

Actual behavior

This is the actual output:

> val it: unit = () <-- This line is missing in VS 2019

> val sum: a: int -> b: int -> int

> sum 1 2 3;;

  #interactiveprompt "hide"
  ^^^^^^^

stdin(3,1): error FS0003: This value is not a function and cannot be applied.

Known workarounds

None.
