Backlog: when a feature is updated on the Feature Backlog, it disappears from it until the page is refreshed

Issue Summary

When using the Feature Backlog, if one Feature is opened and updated, after saving/closing, it will disappear from it, and will only re-appear if the page is refreshed. Other Backlogs (like Epics/Stories) don't have the same problem.
See one example:
The feature can be seen on the backlog:


After saving the update, it disappears:


And only after the refresh of the page it appears once again:

Steps to Reproduce

1. Go to the Feature Backlog
2. Select a Portfolio/Program + PI
3. Open one Feature and update it, save/close
4. See how the Feature is not present anymore
5. Now refresh the page and see how it re-appear

Expected Results

After saving a Feature, it would be visible on the backlog without the need for a refresh of the page.

Actual Results

A refresh is needed to make the Feature appear on the backlog

Workaround

A refresh is needed to make the Feature appear on the backlog
