I am sorry for late response. I just tested and it does not work. The same as it was before

[Balastrong]

@maksymskuibida on the code sandbox you provided it seems to be working (make sure to stop the dev server and run yarn dev again after installing the package)
I tried to fork the demo here.

If you have a more complete example where it's still broken please share it so I can give it another try :D

If tests are passing, let's merge this. Don't let perfect be the enemy of better :)
