Altering selections should not cause the sidebar to reload

[Bad-Science]

Describe the bug
Whenever the user selects or deselects a listing or section, the sidebar is completely reloaded and redrawn, causing any listings that were expanded to collapse. This is very jarring and unpleasant, especially if you are selecting or deselecting from the sidebar itself.

To Reproduce
Steps to reproduce the behavior:

1. Select a listing
2. Expand the sidebar
3. Expand the listing in the sidebar
4. Select or deselect a section from that listing OR select another listing
5. Observe the sidebar updates to reflect the selection change, BUT the listing collapses in the sidebar

Expected behavior
The sidebar should update to reflect any selection changes, without reloading the entire component or otherwise causing expanded listings to collapse.
