[MCPE-113827] Raid bar appears in the nether at coordinates of overworld raid

When traveling to nether coordinates that correspond 1:1 with overworld coordinates where a raid is occuring, a raid bar appears.

Steps to reproduce

Make a safe village in the overworld with a single bed and villager enclosed in a lit room near 200, Y, 0.
/effect @s bad_omen
Wait for the first raid wave to spawn.
Go to the nether.
Travel to 200, Y, 0 in the nether.

Expected result

Nothing special happens at 200, Y, 0 in the nether.

Actual result

The raid progress bar appears when you reach 200, Y, 0 in the nether.

I was exploring a part of the Nether I'd never been in before in an attempt to generate new Nether Update chunks (as I don't often play Bedrock, it hasn't been updated yet) and a Raid bar appeared at the top of my screen. It lasted for maybe a minute before disappearing and displayed there was one remaining raid mob. There is a village in the Overworld that is in a raid which I've never completed, and only one raid mob remains. I think that might be connected.
