Placing a Carved Pumpkin first and then a Copper Block does not trigger Copper Golem spawning

Bug Description: In Minecraft: Bedrock Edition (MCPE) v.1.21.111, the Copper Golem fails to spawn when following the placement order of "first placing a Carved Pumpkin, then placing a Copper Block". However, if an additional Carved Pumpkin is placed next to this Copper Block, the Copper Block will interact with the first-placed Carved Pumpkin and eventually spawn a Copper Golem, which violates the normal spawning logic of the Copper Golem.

Special Exception: If the first-placed Carved Pumpkin is positioned directly above the Copper Block, placing a second Carved Pumpkin next to the Copper Block (in any direction except above) will not trigger the interaction between the first Carved Pumpkin and the Copper Block. Instead, the second Carved Pumpkin will react with the Copper Block to spawn a Copper Golem, while the first Carved Pumpkin remains unchanged.
