Affected version

After (but also before) #7659

Steps to reproduce the bug

Search something (note: this might happen for other fragments, too); then press Android's square button (to view recent apps) and rotate the device at the same time; then go back to the app.

Expected behavior

All of the search items loaded so far are shown instantaneously, like what already happens when the app just resumes from recents (e.g. because its state was saved to disk after a RAM shortage).

Actual behavior

The (search) fragment starts reloading the list from the beginning.
