A structure block gives no warning when the structure would cut off outside the height limit

Description:

When attempting to place a block above y=320, an error message stating that this is not possible is displayed.

But when loading a structure block, no warning message is shown if the structure bounding box goes partially or entirely above y=320 (or below y=-64 for that matter).  When the structure gets cut off, or not generated at all, it still gives a success message like "Structure loaded from '<folder>/<file>'"

To Reproduce:

• get a structure block and place it near world height:
  • /teleport @s ~ 318 ~ 0 40
  • /setblock ~ ~ ~2 minecraft:structure_block
• have it load something that would go above the world height:
  • open the structure block interface, and in Structure Name, paste for example, igloo/top, then hit "LOAD"
  • open the interface again, and hit "LOAD" again.
