We don't want to use flow control like `break` statement into the basic `FOREACH_MAIN_ID` macro, as this is a nested loop. When refined behavior is needed (like breaking whole iteration, or just skipping to next ID type), FOREACH_MAIN_LISTBASE and FOREACH_MAIN_LISTBASE_ID macros should be used instead. Based on D4382 by @campbellbarton (Other potential solution, using flow control macros: D4384).
