Portal Messages not appearing

So, whenever you enter a portal (Nether or end), normally a message that says "Entering the nether" and/or "Leaving the end" would appear and that teleport noise happens. It's been happening ever since singleplayer became multiplayer-managed (1.3).

What I expected to happen was...:
Hearing the teleport noise upon entering the portal.
Seeing the "Entering/Leaving the Nether/End" message

What actually happened was...:
Hearing the teleport noise after spawning in the nether.
Seeing "Downloading Terrain"

Steps to Reproduce
1. Create a nether portal or repair an end portal.
2. Enter the portal.
