Possible Quartus 24.1 bug?

Here is the code:

interface myif
#(
   parameter int W = 1
)();

  typedef struct packed { logic [W-1:0] x; } MYSTRUCT;
  MYSTRUCT s;
  modport src ( output s );
  modport dst ( input s );
endinterface

module top;
   myif #( .w( 5 ) ) test_if();
   
   test test_module
   (
       .foo( test_if )
   );
endmodule

module test
(
   myif.dst  foo
);
   typedef foo.MYSTRUCT MYSTRUCT_COPY;

   $info( "%0d %0d", $bits( foo.MYSTRUCT ), $bits( MYSTRUCT_COPY ) );

   MYSTRUCT_COPY q;
   assign q = foo.s;
endmodule

Surprisingly, the info message will print "5 1" instead of "5 5". And for the assign Quartus will complain that it had to crop the 5 bit wide foo.s to match the 1 bit wide q.

When processing the typedef, Quartus uses the interface definition's default W value instead of the actual value of the actual interface port. I believe that, according to the standard, that is not the expected behaviour.
