Incorrect hierarchical reference in error message

[udif]

Describe the bug When testing the following code (failing to add packed by mistake):

module t40;
typedef struct {
        logic a;
        logic b;
} t;
t x, y, z;
assign z = x & y;

endmodule

Yields the following error message:

% slang  udif_tests/t40.v
Top level design units:
    t40

udif_tests/t40.v:7:14: error: invalid operands to binary expression ('t40.t' and 't40.t40.t')
assign z = x & y;
           ~ ^ ~

Build failed: 1 error, 0 warnings

Additional context I expect the test to fail, but the hierarchical reference t40.t40.t is meaningless.
