I cannot seem to get <fromto[x.y]:a,b> to work when a and/or b are <embed> token groups.
E.g., I think the following five should be equivalent, but I do not get a pure application (or any?) of the embed in the second through fifth cases (even though they differ a bit):
Works:
embed:_offload_I/zPDXLrl.pt,
score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, source_furry, professional anthro shark portrait, dramatic lighting, dark background,wearing business suit
Does not seem to work as expected:
<fromto[0]:embed:_offload_I/zPDXLrl.pt,embed:_offload_I/zPDXLrl.pt>,
score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, source_furry, professional anthro shark portrait, dramatic lighting, dark background,wearing business suit
<fromto[0]:embed:_offload_I/zPDXLrl.pt|embed:_offload_I/zPDXLrl.pt>,
score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, source_furry, professional anthro shark portrait, dramatic lighting, dark background,wearing business suit
<fromto[1]:embed:_offload_I/zPDXLrl.pt,embed:_offload_I/zPDXLrl.pt>,
score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, source_furry, professional anthro shark portrait, dramatic lighting, dark background,wearing business suit
<fromto[1]:embed:_offload_I/zPDXLrl.pt|embed:_offload_I/zPDXLrl.pt>,
score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, source_furry, professional anthro shark portrait, dramatic lighting, dark background,wearing business suit
I varied the start and end from 0 to 1 (I also tried values in between) and tried both "," and "|" as the divider between a and b (as per docs), where a and b were both the same embed.
