Fix document re-fetching when scrolling up in search Queue View

Note: reproducible in LTS 2021 only (tested in nightly-2021)

Steps to Reproduce:

1. In Web UI, navigate to a drawer item configured with a search (e.g. default Search)
2. Perform a query and observe results loading
3. Select a Document from the results (in either Grid or Table view)
4. Observe Queue View appearing in the drawer sidebar
5. Shortly after selected Document loads, attempt to briefly scroll up in Queue View

Expected behavior: Queue View scrolls up, loaded Document remains on page without re-fetching.

Actual behavior: when scrolling up, the selected Document will be re-fetched several times. Visually observed by the Document flickering when reloading, and corresponding requests seen in Dev Tools > Network tab (initiator main.bundle.js:12654).
