End crystals can't be placed on burning bedrock or obsidian

The bug

You can't place end crystals on fire that's on top of bedrock or obsidian blocks.

Expected behavior

Since end crystal entities with a bedrock or obsidian support block display fire in its position, the possibility to place end crystals on burning bedrock or obsidian should be there.
