This bug was introduced in 24w45a.
Steps to reproduce (a video is attached):
Summon a shulker.
Build a tripwire directly above the shulker.
β Notice the tripwire doesn't get triggered when the shulker opens.
Enter survival mode to aggravate the shulker.
β Notice the tripwire doesn't even get triggered when the shulker opens fully.
Alternatively, this can also be reproduced with pressure plates:
Summon a down-facing shulker.
Build a pressure plate directly below the shulker.
Enter survival mode to aggravate the shulker.
β Notice the pressure plate doesn't get triggered when the shulker opens fully.
