Similar to MC-279517, MC-227097, MC-273945, and MC-902, if you replace the obsidian in the End pillars and respawn the Ender Dragon, any blocks inside them are completely deleted.
How to reproduce
Be in the End with the Ender Dragon not alive
Replace some of the blocks in the obsidian pillars with blocks of your choice
Respawn the Ender Dragon
Expected result
Your blocks would not be deleted. They would either not be replaced by obsidian or drop as items.
Observed result
Your blocks are completely deleted.

Surprised this wasn’t fixed with the end portal, end platform and exit portal cases.
MC-272790 would also count as a related issue, would it not?
Can confirm:
