steem-engine api history order problem for multiple txs in one block

I've been worrying about this edge case, and it turns out that it's actually random.

For instance, in block 1896844,
https://steem-engine.rocks/b/1896844

there are two txs of @steemfinex (this is a very rare case and thank you for using it :)

when history is called, it returns the order randomly.

Same block, so timestamp is the same, so no way to distinguish. no tx order is returned, so no way to sort.

Any other way to resolve this than fetching the block?
=> my solution is adding txid as the second sorting key

Hopefully, the order will be fixed.
