I see no reason to believe this is a bug, it is likely this is intentional behavior
Video attached.

This doesn't seem to be fixed in 21w13a it still takes about a second to mine
Yes, this issue doesn't appear to be fixed in 21w13a.
Can confirm in 21w14a.
Maybe intentional because it's mined faster with axes.
Can confirm in 21w15a.
Can confirm in 21w16a.
Can confirm in 21w17a.
Can confirm in 1.17.

Can confirm in 1.17.1 Pre-release 3.
Can confirm in 1.17.1.

Can confirm in 21w43a.
I am also able to confirm this behavior in 21w43a. Here are some extra details regarding this problem.
The Bug:
Big dripleaves are not mined instantly unlike other plant-like blocks.
Steps to Reproduce:
Place down a big dripleaf.
Switch into survival mode and begin mining it.
Take note as to whether or not big dripleaves are mined instantly.
Observed Behavior:
Big dripleaves are not mined instantly and take around half a second to be mined.
Expected Behavior:
Big dripleaves would be mined instantly, just how other plant-like blocks are mined instantly.

Can confirm in 1.18 Pre-release 1. I think that this is caused by this piece of code:
net.minecraft.world.level.block.Blocks.java (Mojang mappings, 1.18-pre1)
...
public static final Block BIG_DRIPLEAF = Blocks.register("big_dripleaf", new BigDripleafBlock(BlockBehaviour.Properties.of(Material.PLANT).strength(0.1f).sound(SoundType.BIG_DRIPLEAF))); /**Big dripleaf has a strength of 0.1, meaning it is not instantly mined.*/
...
Replacing strength(0.1f)
with instabreak()
should fix the issue.
Can confirm in 1.18.
Can confirm in 1.18.1.
Can confirm in 1.18.2.
Can confirm in 1.19.

Can confirm in 25w6a.
I can confirm that you do not insta mine it, but it doesn’t seem like one second to me. It is less than 1 second.
