When creating a PSBT, only include the BIP32 derivations in each input for the spending path this PSBT was created for. This is to workaround Bitbox only providing a single signature per input. Most likely other signing devices will have this behaviour too in the future. See https://github.com/wizardsardine/liana/pull/706#issuecomment-1744705808.
