If you go far enough from them, they disappear from your view (while other blocks are rendered normally, even beyond them) just like mobs do (even though they are still there).

These blocks do actually render as entities. This allows them to move (chests opening, banners waving, etc) and display differently based on their data (banner patterns, sign text, etc). As such, they render in a much more laggy way than normal blocks, so they have a shorter view distance.
