Finalizing a psbt with 4 inputs creates an invalid hex transaction

Hi,

I have a 2 of 3 segwit multisig wallet. When I create a psbt with 4 inputs and finalize it with Libwally 0.8.0 the raw hex gets rejected by Bitcoin Core `bitcoin-cli testmempoolaccept` with an error: `bad-witness-nonstandard`

It seems to work just fine with 3 inputs or less though.

This is a mainnet wallet and I do not want to lose privacy by sharing the data. I will attempt to create a testnet tx and share the details here later.
