Can't "Pick Block" cauldrons with liquid or powdered snow inside

Thats how its meant to work. There isn't a full cauldron block, and thus isn't pickable.

yeah you can't /give @p Filled_Cauldron

But there are translation texts for lava cauldron and water cauldron. But they are unused as they are not items. So I guess they SHOULD be items, but did not get implemented yet. Why else would they get text in the translation files? F3-screen only shows the name-strings anyway, and if they are not (creative) inventory-items, they need no names in the textfiles. But as this ticket is already assigned, that shows that some solution (I guess making them items/proper blocks) is being looked into...

I notice this also applies to creative mode's pick block, and pick block +NBT. So it is not just that it is because it is filled, but more so the filled cauldrons not supporting the middle click altogether.

Should it be fixed when "pick block" filled cauldron it gives you nbt+ tag which it gives you function to place cauldron what inside of it there's a purple tag that says 'Water Cauldron' for example.

Ctrl+Middle Click (If you're not pressing middle click with a mouse your finger hurts? sorry, use custom keybind to pick block control)

To get cauldron on water with your crosshair it gives you a cauldron with nbt+ tag on it

should it not fixed, but i don't think it should be WAI

A similar issue is with potted flowers. After they wiped out nbt states for blocks, there are blocks that have no linked item. "potted_lily_of_the_valley" instead of giving a flower pot, gives you the flower it contains when you middle click it, and nothing if you ctrl+middle click. Likely they forgot to direct lava/powdered snow/water cauldrons to cauldrons, or their respective buckets of the liquid.
