php 7.4 DOMDocument::loadHTML(): Tag figure invalid in Entity

rgfx

I getting this error in wordpress,

Warning: DOMDocument::loadHTML(): Tag figure invalid in Entity

$post->loadHTML(mb_convert_encoding($the_content, 'HTML-ENTITIES', 'UTF-8'));

I have the extension mbstring enabled. I read that I might need php-xml7.4 but that doesn't appear in the extension.

Is there a place to download extensions?

Thanks

@rgfx I fix this myself by doing this.

libxml_use_internal_errors(true);
$post = new DOMDocument('1.0', 'UTF-8');
$post->loadHTML(mb_convert_encoding($the_content, 'HTML-ENTITIES', 'UTF-8'));
