Facebook embeds use wrong locales

[Cry0nicS]

Version 4.7 brought awesome support for Facebook embeds. The issue is that the language / locales in wrong and keep changing for no particular reason.

Example: I have a website where Timezone is set to Bucharest, language to english, but the Facebook embeds where for 2 months in Ukrainian and now it's using nl_NL.

Example: ​https://esportsmedia.ro/highlights/hearthstone-highlights/golakka-winning-move-angeloshaggy/

There's no way to control it.

Issue persists in 4.8

I tried executing something like this, but with no success.

<?php
add_filter( 'the_content', 'facebook_sdk_replace' );
function facebook_sdk_replace( $content ) {
    if ( is_single() ) {
        $content = str_replace("nl_NL", "en_US", $content);
    }
    return $content;
}
