mustPayToOtherScriptWithDatumInTx when used with mustSpendScriptOutput does not attach datum to the tx

[smunx]

Summary

When using the mustPayToOtherScriptWithDatumInTx, mustIncludeDatumInTx and mustSpendScriptOutput in the offchain code it dose not attach the datum to the transaction.
The txOutDatum is yielding only the datumHash when doing a check inside the getContinuingOutputs.

Steps to reproduce the behavior

Create a offchain tx with mustPayToOtherScriptWithDatumInTx, mustIncludeDatumInTx and mustSpendScriptOutput
The script output is spent and also to certain amount is paid back to the same script.

Actual Result

onchain only gets the datumhash and not the datum itself.

Expected Result

onchain should should the datum not just the datumhash.
