I'm working with a snippet that has a class that can be applied to it to make it full width. This snippet represents a carousel with some predefined slides. Upon creating it, things look fine in the default state. Once I apply the global class at the top level, the slide has it's
Page Content rendering stripped which cannot be reapplied through ee which says an error occurred. Interestingly enough, I am also not able to reset the final layout after this happens due to the same error. Viewing the snippet in the shared layout shows the page content rendering as it should kind of pointing to the rendering being alright as far as I can tell. In the logs I see the following error:

The json device for the page with the snippet has its layout set to JSONLayout. There are no renderings in that device but this is consistent with other pages for the site. I've tried removing the layout in the json device to see if that would change anything but no dice. Any info about this would be appreciated.
