- Add global class to an element
- Switch to the ‘before’ editing state
- Go to Design > Pseudo Classes tab, and add ‘example’ for the Pseudo Content
- Add a height of 1 rem, and add a new transition with whatever settings
- Check the front-end for the ::before element. You’ll see the height apply, but not the transition.
If using block styling instead of a global class, it works correctly.
