Settings navigation: selected category out of viewable range after select

Expected behavior

If you navigate through the settings menu categories, the last selected category should always be shown on the screen.

Current behavior

If you open the setting menu the available Personal and Administration categories are shown on the left part of the screen. If you now scroll down and select e.g. the category Administration - Logging the relevant content is correctly show on the right part of the screen but the menu itself is refreshed so that the previously selected category cannot be seen anymore.

Steps to reproduce

1. Open the settings menu.
2. Scroll down the menu and select the category Administration - Logging.
3. The relevant content is correctly shown but the selected category itself is not viewable anymore because the menu is refreshed.
