Background of the issue:
I am trying to ensure that the WooCommerce Processing order Email is correctly aligned according to the customer's language. My site's default language is English, which is left-to-right (ltr), but the customer placed an order from the Hebrew website, which is right-to-left (rtl).
Symptoms:
The Processing order Email sent to the customer is mostly aligned rtl, which is correct for Hebrew, but the heading is incorrectly aligned ltr.
Questions:
How can I ensure the email heading aligns correctly with the customer's language direction?
