BIP39 WordList passphrase limited to 10 words

[Bill397124]

Wallet with a 12 or 24 BIP39 words passphrase cannot be recovered using a Jade:

BIP39 passphrase using method: WordList.

• Not possible to enter more than 10 words.
• After entering the 10th word the wallet is automatically created, no user confirmation the passphrase is fully entered.

BIP39 passphrase using method: Manually.

• Now entering more than 10 words is allowed.
• But still number of characters are limited (max 100 I think).

I'd second that this should be expanded (is there a reason for any limit?), at least to 12 BIP words so that a seed could be used as a passphrase almost like a "2-factor" 2-of-2 multisig. At a minimum, the user should be informed when entering the 10th word that it will be the last one, since the behaviour of going straight into the wallet at 10 words could cause confusion (and be a real problem if they have an existing wallet with more than 10 words that they need to access).

For all BIP39 passphrases, the user should be able to see the passphrase in full on the screen after finishing typing it in, to confirm it before entering the wallet, with scrolling as necessary. This is essential, since a user may otherwise unknowingly enter a different wallet and even send funds there, if they haven't previously noted and known to check a fingerprint code.
