VB boolean literals not highlighted as keywords in SymbolDisplay.ToDisplayParts

Create a C# project and a VB project referencing it. C# file:

public class CS
{
    public const bool Const = true;
}

VB with completion invoked at |.

Module VB
    Sub M()
        CS.|
    End Sub
End Module

Expected behavior: True is colored as a keyword Actual behavior: it's not

This is because in the result of calling SymbolDisplay.ToDisplayParts on the field, the part with the true keyword has a kind of SymbolDisplayPartKind.NumericLiteral as opposed to SymbolDisplayPartKind.Keyword (so this bug is in the compiler).
