CurrentCulture is not preserved between submissions of desktop fsi

[KevinRansom]

dotnet fsi appears to, but that may just be an accident.

Repro:
Start fsi
paste in this script

open System
open System.Globalization

System.Globalization.CultureInfo.CurrentCulture <- System.Globalization.CultureInfo.GetCultureInfo("nl-NL")

System.Console.WriteLine(System.Globalization.CultureInfo.CurrentCulture);;
System.Console.WriteLine(System.Globalization.CultureInfo.CurrentCulture);;

observe that currentculture is different in both submissions.

dotnet fsi being right

@KevinRansom This only happens when "--gui" event loop support is enabled, as in .NET Framework fsi but not in dotnet fsi. I'm not sure it should be fixed.

I guess we should consider whether we want some kind of event loop support for dotnet fsi. We haven't exactly documented this difference.

There is no need to fix this. It is how it has always worked.
