3107203 - Print preview result can be different comparing already processed and not yet processed BRF+ outputs

You have such a Purchasing document (for example Purchase Order), in which you use the S/4hana output control output (a.k.a BRF+ based) determination logic.
You have such a document in which you have already succesfully processed outputs (completed status), and you also have not yet processed output type(s) ("to be processed" or "in preparation" status)

You notice that previewing these two status typed outputs behaves differently.

In debugging you also notice that the call stack is fully different at previewing such outputs:

Callstack (from bottom to top) of not yet processed output's preview (in this case this is an example of a legacy output form's processing, not PDF with fragements case, but the overall logic is same):
