End Portal Room spawn point

Bug: Spawn point set to surface instead of correct Y of bed set in end portal Room.

Device: Google Pixel 2, Android version 9
Minecraft App version: 1.8.1.2

Recreation Steps: find portal Room. Place bed. Sleep in it or click it to set Spawn point. Fill portal to create. Jump in portal. Find dragon. Destroy all but 1 end crystals. When running to last crystal pillar get hit by a breath shot that bounces you to another breath, and to a 3rd which kills you. Respawn in village far higher but at same X Z as bed.

Ok, obviously the steps to recreate were specific but rediculous. This happens so often now that it's expected. Whenever I set my Spawn point to a bed in the portal Room I'll expect to Spawn on the surface no matter how I die in the end.
