FIX: Rendering a single item in a grid (#24464)

Browse Source 
Should fix https://meta.discourse.org/t/-/285768.

Appending without cloning was causing the item to be removed from the
DOM but on a 1-item grid we skip the rest of the grid's rendering,
hence the item was never re-inserted. Cloning ensures we don't remove
the item during processing (it does get removed later on when rendering
the grid's columns).
