Loading a structure into a structure breaks the game for few seconds.

When I load a structure into a structure the game breaks for few second ( depends on how big the structure is). It happens to me because I use structure blocks a lot and I have to wait seconds to minute to let the bug go away.

Sry i cant get a whole video bc of the 10mb limit.

Steps to reproduce:-

1. Save a decent size of structure in a structure block (MCPE)
2. Take another big structure and load the structure into it.
3. The structures should be something excluding air it depends on the size

Observed Results-
The game breaks for few seconds and the mobs freeze, breaking or placing blocks wont show, probably the random tick speed increases to insane amounts.

Expected Results-
It should load it smoothly and no randomtickspeed drop should occur.
