E.g. Ionic framework automatically adds classes like "hydrated" to certain elements. But Compose web erases them when re-composing

11/05/2021, 10:11 AMI understand why it was built that way, but in the real world, many existing JS libraries like to mess with classes & attributes.
It's technically possible for Compose Web to be less destructive (e.g. don't remove a class that Compose itself didn't add) which would increase compatibility with existing libraries.
