Topic on Extension talk:YouTube

Google PageSpeed Insights says too late on process embed YouTube in my site.

This extension has $wgYouTubeEnableLazyLoad option but using non-standard technique.

So, I make a simple patch to append loading="lazy" on ‎<iframe>.

Please test it if you were in trouble because of SEO.

Thank you.
