Add the loading=lazy attribute to iframes coming from oEmbeds in content
About this plugin
This plugin adds the loading=lazy attribute to iframe elements coming from oEmbeds. In WordPress 5.5, loading=lazy is added to images per #44427, and in 5.7 it is being added to iframes as well per #50756.
This plugin will be obsolete by the time WordPress 5.7 is released. When that happens, this plugin will do nothing.
