Sculk Shrieker count resets when entering exit end portal

This is related to MC-6431 as it has to do with the end portal and removing things, but if you were to activate a sculk shrieker a few times and enter the exit end portal, the counter resets and you will have 3 counts until the warden can spawn again. The only way the counts are meant to go away is after waiting awhile or dying, but this also seems to reset it back to 0.
