Plugin seems to break wpautop on pages published in classic editor

With this plugin activated, automatically-inserted <p> tags are removed from older pages (perhaps also posts, but I didn’t test) published with the classic editor. Deactivating this plugin was the only way for me to fix it. I assume this is related to the wpautop function.

For me, this is not an urgent issue. I’ll just leave the plugin deactivated until a future fix. I’m just posting this so the devs are aware of it.
