First name with hyphen is merged into last name after save

What happened?

Description

When submitting separate first name and last name on the checkout then when the first name contains a hyphen "-" then after save the first name is blank the last name field contains the first name and last name.

Steps to reproduce

1. submit first name and last name separately
2. Make sure first name contains a hyphen "-" .e.g. "Chi-la".
3. Last name can be anything e.g. "Smith"
4. Submit the form.
5. Refresh and now the first name field is empty and the last name contains "Chi-la Smith"

Expected behavior

I would expect first name field contains "Chi-la" and last name contains "Smith.

WARNING! Stripe does not not support hyphen "-" in the name so perhaps better to output this:

First name: "Chi la"
Last name: "Smith

Alternatively strip the hyphen "-" from the stripe payment request generation.

I noticed this issue as a customer couldn't pay due to Stripe having a JS error.
Uncaught (in promise) TypeError: paymentResponse.redirectData is undefined
due to no first name stored on the order.

Actual behavior

First name: (blank)
Last name: "Chi-la Smith"
