PIN change or setup of model One broken when using computer keyboard

[bosomt]

Describe the bug See both videos, first for PIN setup and second for PIN change. When you confirm PIN via computer keyboard then in second dialogue there is always one character already in PIN field. I was able to replicate on dev version and on production version.

Steps to reproduce:

1. Try to change or set PIN code on model One
2. Confirm PIN via enter on keyboard
3. Observe modal behavior, there is always one character pre-filled.

@Hermez-cz How about making it impossible to enter PIN from the keyboard? Not to solve this bug, but because it makes the blind matrix meaningless and the user can unnecessarily reveal the PIN. But I guess that would complicate the the work of our @trezor/qa?

Didn’t know this was possible. I would restrict it. 🤷🏻‍♂️
