Copper golems lose all data except name when turning into a statue

The bug

The health, potion effects, fire time, tags, left-handedness, and other data of copper golems is not preserved when they turn into a statue. In Bedrock Edition, all of this information actually is preserved. You can set a copper golem on fire, give it potion effects, and damage it, and turn it into a statue. When the statue is later scraped, all of that state will be restored.

How to reproduce

1. /summon copper_golem ~ ~ ~ {weather_state:"oxidized",next_weather_age:2L,Tags:["blah"]}

2. Wait for it to turn into a statue

3. Use an axe to turn it back

4. /tag @n[type=copper_golem] list

Expected result

Copper golem should (still) have the “blah” tag

Observed result

The tag was lost

Notes

For my unsolicited opinion, I think it’s silly that Bedrock preserves everything, like potion effects (invisible golem turns to visible statue, then scrapes to invisible again?). However, preserving health and left-handedness I think is important.
