`ItemStack.data` was removed in this preview and now there is no way to differentiate between stacked by data items. For example, there is no way to differentiate between Stone and Granite since they are both `minecraft:stone` and the `data` property has now been removed.
Example Script:
import * as s from '@minecraft/server';
const player = s.world.getAllPlayers()[0];
// Assume the player is holding granite.
const selectedItem = player.getComponent('inventory').container.getItem(player.selectedSlot); // This would return an ItemStack of granite.
if (!selectedItem) throw "Not holding an item, please hold granite and run '/reload'.";
// However, there is no way to know if it is granite because there is no data property on the item.
console.warn('selectedItem.typeId:', selectedItem.typeId /* returns 'minecraft:stone'. */);
for (const property in selectedItem.type /* returns ItemType with only one property, 'id', which equals 'minecraft:stone'. */) console.warn('Property in selectedItem.type:', property, 'Property value:', selectedItem.type[property]);
console.warn('selectedItem.data:', selectedItem.data /* returns undefined. */);
// So, there's no way to know if the item recieved is stone or another stone variant. This also applies to many other blocks and items.

I found a workaround, it's pretty nasty, but it works:
Give and clear command still use data.
You can use these commands with the typeId of the item and various data values (0-15) to detect if the amount of the item changes.

Is this still an issue in the latest version? If yes, could you please add it to the affected versions (or mention it if you are not the reporter)?

Yes, this is still an issue.
Some blocks that still have not been separated:
slabs (eg. brick slabs are still `minecraft:stone_block_slab`)
flowers - many flowers are still under `minecraft:red_flower` and `minecraft:yellow_flower` (eg. oxeye daisy is `minecraft:red_flower`)
walls (eg. brick walls are still `minecraft:cobblestone_wall`)
This affects a lot of items, such as logs.
For example, defining:
Results in 'value' being undefined, but 'value2' being a populated ItemType.
