breaking changes with Group, elem_classes and css

[lhoestq]

Describe the bug

I updated https://huggingface.co/spaces/infinite-dataset-hub/infinite-dataset-hub from 4.X.X to 6.8.0 and elem_classes doesn't work for gr.Group() anymore. I also had to pass !IMPORTANT to every single css attributes in my buttons (which also rely on elem_classes for css)

finally for some reason some CSS stopped working altogether like animations
