Unexpectedly falling in void when fly into unloaded chunks

While traveling faster then the loading chunks, many players can't go beyond the loading chunks and in before versions when using elytra and reaching to loading chunk, player sort of used to slide but just hour back in the end, I was flying back to center of the world but I was faster then loading of the chunks and somehow instead of going down slow (how it used to and suppose to) I instantly fell in void and elytra also stopped to fly.
