Sender email address shows 'to' address instead of 'from'

[jesuismaxime]

Description

Sender email address in the actual email header is equal to the 'to' email address even if {{ submission.fromEmail }} shows the right email address. The sender name (fromName) shows the right data.

We use a custom fetch()/formData setup to call the action, not a traditional Twig template, but all the datas are visible in the post headers.
