[MC-9644] Launched falling_block entities do not travel through portals

I made an anvil-launching cannon with TNT and redstone.

What I expected to happen was the anvil would be sent into the nether like an arrow or other moving entity.

What actually happened was the anvil passed through the portal blocks as if they weren't there and landed on the other side.

How to reproduce

Place a nether portal block (make sure it is not on the ground)
```
/setblock ~ ~ ~3 nether_portal
```
Place a gravity-affected block above it
```
/setblock ~ ~2 ~3 sand
```
→ ❌ The block falls straight through the nether portal block without being transported to/from the nether

Confirmed. Also applies to all FallingBlock entities.

Is this still an issue in the current Minecraft Snapshot 15w49b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
