Converted mobs do not keep CanBreakDoors tag

Contrary to the 24w37a changelog, Zombies that convert to Drowned do not keep the CanBreakDoors tag.

To reproduce:

1. /summon zombie ~ ~ ~ {CanBreakDoors:1b}
2. Place the zombie underwater until it converts to a Drowned
3. /data get entity @n[type=drowned] CanBreakDoors
4. Notice that the CanBreakDoors tag is 0b, not 1b as expected

There is a small chance the newly spawned zombie will naturally be able to break doors based on regional difficulty, so you may need to repeat the experiment.
