 * Everytime i put some blocks within a group block, if i hit undo button, it doesn’t
   undo the action. And i get an error on the console:
 * Uncaught TypeError: e.className.split is not a function
 * Is this an expected behaviour?

 * Hi [@avagp](https://wordpress.org/support/users/avagp/),
 * This is certainly not an expected behavior. I tested the undo functionality on
   my test site. I tried different setups, inserting blocks into a group block, 
   then undoing this action. Everything works fine on my end. Something is likely
   blocking this button’s functionality.
 * Have you tried to perform a plugin/theme conflict test? You could also try using
   a different device to test.
 * Give these a try and let us know how it goes in your next response.
