Comment:

 == TODO

 1. This address cannot be parsed by PHPMailer `From: "test<stage"
 <test at example.com>` It breaks with the first angle bracket.
 [https://github.com/PHPMailer/PHPMailer/issues/3235 Reported Upstream]

 2. Reply-To is unnecessarily inconsistent in PHPMailer. I will leave it
 away for now, while preserving the same format (as it's not relevant from
 the `wp_mail` wrapper). This only affects the test.
 [https://github.com/PHPMailer/PHPMailer/issues/3234 Reported Upstream]

 It's gonna be hard, because this is blocking two other reports. Problem
 with all this is that we are going so deep into the mail function, that a
 ton of problems are arising in an spiral ones blocking each other and then
 merging changes among all is a party :(
