Comment:

 Hi there, welcome back to WordPress Trac! Thanks for the report.

 Setting the type to `text/html` using the `wp_mail_content_type` filter
 changes the `Content-Type` header of the email, but does not perform
 anything else to actually convert the message to HTML, you still need to
 do that yourself.

 > When this plugin is active and I have to try to reset my password I have
 the following text into a variable `$message`

 If you look at the page source at that point, you'll notice that even
 though the browser renders the message as a single line, it actually
 consists of multiple lines in text format,
 {{{
 string(362) "Someone has requested a password reset for the following
 account:

 Site Name: WordPress Trunk (dev)

 Username: admin

 If this was a mistake, ignore this email and nothing will happen.

 To reset your password, visit the following address:

 http://develop.wordpress.test/build/wp-
 login.php?action=rp&key=...&login=admin&wp_lang=en_US

 "
 }}}

 So you'll need to run something like `nlbr()` to convert it to HTML:
 {{{
 if ( ! function_exists( 'wp_mail' ) ) {
         function wp_mail( $to, $subject, $message, $headers = '',
 $attachments = [] )
         {
                 $message = nl2br( $message );
                 var_dump( $message );
         }
 }
 }}}
 which would then result in:
 {{{
 string(434) "Someone has requested a password reset for the following
 account:<br />
 <br />
 Site Name: WordPress Trunk (dev)<br />
 <br />
 Username: admin<br />
 <br />
 If this was a mistake, ignore this email and nothing will happen.<br />
 <br />
 To reset your password, visit the following address:<br />
 <br />
 http://develop.wordpress.test/build/wp-
 login.php?action=rp&key=...&login=admin&wp_lang=en_US<br />
 <br />
 }}}

 > In WordPress 5.7.2 it is the same, but the URL is with strange brackets
 - `<http://local-env.dev/wp-
 login.php?action=rp&key=...&login=exampleUser&wp_lang=en_US>`

 The brackets were removed in [47086] / #44589 for WordPress 5.4.
