Will the generic TObjectList bug with serialising to JSON get fixed?

When I try to serialise a generic TObjectList to JSON doing something like this:

Response.Content  := TJSON.ObjectToJsonString(MyObjectList);

I get the error Type tkPointer is not currently supported. I am using 10.3 and I believe this bug (21685) has been around since XE8. I am currently having to think of workarounds and trying to find the best solution. It would be really useful if they would fix this bug, or give some idea of when it will be fixed, does anyone know?
