White screen while capabilities and capability sets are loading when opening a role for edit second time

Steps to reproduce:

1. Login to evrk2 ( )

2. Click on the name of any existing role in the second pane

3. In the third pane, click on “Actions“ button → Select “Edit” option

4. Click on “Cancel” button

5. In the third pane, click on “Actions“ button → Select “Edit” option

Expected result: “Edit role“ pane is opened. Loading animations are shown in both “Capability sets“ and “Capabilities“ accordions for some time. Then lists of capability sets and capabilities are loaded.

Actual result: “Edit role“ pane is opened. It only contains “Unassign all capabilities/sets” button and “Collapse all” link - the rest of the pane is empty (white space). After some time, the rest of the elements are loaded simultaneously with the lists of capability sets and capabilities.
