It's actually fairly well known in certain circles. It's mentioned in 
the Unravelled series and there was at least one article in Rainbow that 
mentioned it as I recall.

And, no, it wasn't fixed on the Coco 3. I doubt the people writing the 
Coco 3 additions were even aware of it. Although they did patch & 
handling to allow for 24 bit values instead of just 16 bit.
