Find Usages of typedef-ed struct

I've recently noticed two problems with typedef-ed struct, such like this one:

typedef struct
{
    int             length;
} Square;

1. The "Open Type Hierarchy" doesn't work.
2. When we have two or more typedef-ed struct that have members with the same name, the "Find Usages" will not search contextually. Meaning it will find all occurrences in all struct. For example with those structs if we search usages of length it will give results of both structs.

typedef struct
{
    int             length;
} Square;

typedef struct
{
    int             length;
} Rectangle;
