977d60c9 - fix: snapshot objs length before super() to avoid re-patching

fix: snapshot objs length before super() to avoid re-patching The _last_patched_idx approach overwrites previously patched chars when cur_item reverts after a figure with text ops. Instead, each do_TJ/do_Tj snapshots len(objs) before super() and only patches from that index.
