Wither and Creeper still don't drop 100% of exploded blocks

Summary:

In update 1.21.0.20 of minecraft bedrock, in its changelog, the TNT explosion drop rate was changed to 100%, however, the explosion drops of creepers and withers have not yet been changed to match with Java Edition

Observed Results:

The rate of blocks dropped by the explosion of a creeper or wither is still the same, so the blocks dropped are not the same quantity as those exploded, making it impossible to rebuild terrain.

In the videos below, I do a quick reconstruction of the locations exploded by the mobs, showing that it is not possible to perfectly reconstruct the exploded location.

Expected Results:

In Minecraft Java, the rate of blocks dropped by these animals, when they explode, is 100%, so the player has no difficulty rebuilding the place after being exploded by these animals.
