New issue view no longer sum up the Story Points from Sub-tasks into Parent issue

The new issue view no longer sums up the Story Points from Sub-tasks into Parent issue.

When using the old view, if you have sub-tasks estimated, it sums up to the Parent Link to display the amount of work that has been estimated. The new issue view no longer presents this feature.
It forces the customers to roll back to the old UI for Jira Software users.
