in this example i would expect that rendering to new take could keep the looping:
This is just a small example for demonstration since usually loops are much longer and probably full song.
If i render an item with 1 bar looping for 150 bars, the rendered take should be also looping 1 bar during 150 bars, but Reaper just renders 150 bars and ignores it's a loop that i am rendering.
Reaper by doing this takes more time for rendering and just eats disk space with no need, and give user extra work for going back to the original looping need.
