[4.x]: If title is used for first name it is stripped when outputting first name

[philipboomy]

What happened?

Description

When outputting first name like this $order->billingAddress->firstName it comes out with "null" if the first name is for example "Miss"

Since we are not blocking the user from entering "Miss" as first name frontend we need it to output "Miss" when using $order->billingAddress->firstName otherwise we end up with empty variables when sending order data to for example shipping fulfilment.

The above is just my opinion. Happy to be proven wrong. Just seeking a solution.

Expected behavior

Output "Miss"

Actual behavior

Output "null"

We're having the same problem, preventing a commerce customer from paying the order.
