Hello. We use discourse! as a web view in our application coded with Flutter. Recently I noticed that the forum membership screen did not open. While doing research, I noticed something like this in the browser console (see image). Could it have something to do with this?

Also in the latest version [(d405305456](https://github.com/discourse/discourse/commits/d40530545607f307b613167a0659e05dd0bda3dc)) the experimental new lightbox does not work. When you click on the image, the image does not appear. There’s just his steamy shape in the background.
