JavaScript for WordPress Forums Gutenberg Development Image tag wrapped with Reply To: Image tag wrapped with


I had this same exact problem. I had a custom plugin that was used for creating custom pagination on posts using a regex pattern and returning the markup through wpautop function in wordpress core formatting.php. Wrapping the plugin to only filter content on the client side, not editors side, fixed it.

If you can’t figure out your issue I would resort to turning your plugins off one by one and see if that fixes it.
