I'm very happy that picket fences can now be waterlogged <3
But while testing this fix, I discovered some other ways in which they don't work like vanilla fences:
1. they can not be placed in water blocks to create a waterlogged picket fence
2. placing water against the hitbox of the fence itself does not create a waterlogged fence, but the animation of placing water from a bucket still plays
3. picket fences can not be placed on top of one another, or below one another (this used to be the case in older versions of minecraft, so maybe a holdover from before?)
4. picket fences fail to place on top of other picket fence blocks when placed against the side of another block, requiring "poles" of picket fences to be constructed top-to-bottom, rather than any freeform way like vanilla fences
while minor, I hope these inconsistencies can be fixed some day <3
