No, mobgriefing is on.
I'm pretty sure this is a real regression.
I have seen no villager breeding since the update to 1.1. I had an established working iron farm that would reliably breed new villagers when I removed some. Now after I removed some villagers the remaining villagers are tossing food back and forth but they still don't breed. I traded with 3 of them just in case that was the issue, but still no breeding.
On another world I have a natural village with 10 villagers and about 15 doors, at least 6 of which are valid, I added 30 doors hoping to get some new villagers to trade with but still no breeding. So I moved 2 villagers out of the village and installed them in a brand new village more than 1000 blocks away from the original village (and any other village, it's a jungle/ocean biome). The new village has 10 doors within 8 blocks of the pair. I traded with the villagers and also gave them bread until they stopped picking it up (definitely more than 3 bread each) but they still don't breed.
This is reproducible in the Windows 10 edition 1.0.4 and 1.0.5. I tried two worlds (both based on the same seed). I tried both a 20x20 portal, and rectangle of 4 8x20 portals.
The Minecraft store does not provide any way to do that, the only link for reporting bugs comes here.
Furthermore, the world template worked until the 1.16 update, which means you broke it.
