Offline send token amount value order messed up

[Trinketer22]

Info

• Browser: (Firefox)
• OS: (Linux)
• Version: https://github.com/MyEtherWallet/MyEtherWallet/releases/tag/v6.6.10-hotfix.1

Steps to reproduce

• Navigate to send offline
• Pick any ERC-20 token
• Let's pick a value 1000 for simplicity
• File gas field accordingly
• Hit "Generate transaction"
• Look what we get in transaction data input

00000000000000000000000000000000000000000000000000000000000003e8
This is what we get in the transaction input data value field.
I'm pretty sure it expects value of different order (I assume * "mwei", but you know better).
More so if we enter decimal like "1000.12345" we would get 0 in the data value field.
Highly likely because of this:https://github.com/MyEtherWallet/MyEtherWallet/blob/main/src/modules/send-offline/ModuleSendOffline.vue#L355
BN can't take fractional AND value has to be put in some wei order first.
Like so for example:web3.utils.toWei(this.amount, "mwei")

Perhaps it's not that simple and we have to store decimals for some of the tokens:https://eips.ethereum.org/EIPS/eip-20 method decimals.
Pretty sure it used to work fine with decimals and everything in way earlier releases
