 I have created my own plugin that overrides the Pluggable function
 wp_mail, but into the variable {{{$message}}}, it is "text/plain". I have
 tried to add a filter to change it to "text/html", but it doesn't work.
 Here is the code of the plugin:

 {{{#!php
 <?php
 /**
 Plugin Name: wp_mail override
 Description: Example plugin wp_mail override
 Author: Example
 Version: 1.0
 Author URI: https://example.com
 */

 function xxxx_set_content_type( $content_type ) {
     return 'text/html';
 }
 add_filter('wp_mail_content_type', 'xxxx_set_content_type' );

 if (!function_exists('wp_mail')) {
     function wp_mail( $to, $subject, $message, $headers = '', $attachments
 = [] )
     {
         var_dump($message);
     }
 }
 }}}

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


 `Someone has requested a password reset for the following account: Site
 Name: example Username: exampleUser If this was a mistake, ignore this
 email and nothing will happen. To reset your password, visit the following
 address: http://local-env.dev/wp-
 login.php?action=rp&key=8CC4r2GttU32W5njL0AU&login=exampleUser&wp_lang=en_US
 This password reset request originated from the IP address 127.0.0.1. `
