PS2: 
The comment just above the line with tested status indicates that the idea always was to mark everything tested. It's just that support for `B` in `TEST_OK_PREWB` was implemented much later (later than the comment), but should have been here.

Additional context, is that the message itself is upgraded in the next patch CB:85092
