Given this C# code:

public interface IThing
{
    IObject { get; set; }
    IDooDad { get; set; }
}

public class AClass : IThing
{
    IObject { get; set; }
    IDooDad { get; set; }
}

public interface IObject
{
    IWidget { get; set; }
    // blah blah blah
}

public interface IDooDad {}

public interface IWidget
{
    string get_description();
    IOther { get; set; }
}

------------

Let's say I want to navigate from interface description to interface description, bypassing other type declarations and member variables, and with the caret at the leading I in the interface name.

/interface \zsI\ze[A-Z]

This works fine for navigating forward, and if I :set hls, all the correct Is are highlighted, but when I attempt to move to the previous match I get no movement.  This approach works as expected in Vim.
