Why browser show Server API for info.html as Apache 2.0 Handler but info.php as FPM/FastCGI?

Environment:centos7+php7.2.
I build FPM/FastCGI as the tutorial say.
build FPM/FastCGI

Show my important configuration in /etc/httpd/conf.d/php.conf.

<IfModule  mod_php7.c>
    <FilesMatch .(php|phar)$>
         SetHandler "proxy:fcgi://127.0.0.1:9000"
    </FilesMatch>
<FilesMatch ".+.html$">
    SetHandler application/x-httpd-php
</FilesMatch>
    php_value session.save_handler "files"
    php_value session.save_path    "/var/lib/php/session"
    php_value soap.wsdl_cache_dir  "/var/lib/php/wsdlcache"
</IfModule>

Assign the same content below with two names info.php and info.html in my vps directory /var/www/html.

    <?php
    phpinfo();
    ?>

Type vps_ip/info.php in browser, show the below output:

Code:
    System  Linux localhost.localdomain 2.6.32-042stab132.1 #1 SMP Wed Jul 11 13:51:30 MSK 2018 x86_64
    Build Date  Oct 10 2018 10:01:57
    Server API  FPM/FastCGI
    Virtual Directory Support   disabled

Type vps_ip/info.html in browser, show the below output:

    System  Linux localhost.localdomain 2.6.32-042stab132.1 #1 SMP Wed Jul 11 13:51:30 MSK 2018 x86_64
    Build Date  Oct 10 2018 10:01:57
    Server API  Apache 2.0 Handler
    Virtual Directory Support   disabled

Why my browser show Server API for info.html as Apache 2.0 Handler,
but show Server API for info.php as FPM/FastCGI?

Try to set FilesMatch for html as below.

<FilesMatch ".+.html$">
    SetHandler "proxy:fcgi://127.0.0.1:9000"
</FilesMatch>

Type vps_ip/info.html ,i got error:

Access denied.

I want to open vps_ip/info.html with apache’s FPM/FastCGI way ,instead of Apache 2.0 Handler way.
