Variants of copper chests are not included in the "Redstone Blocks" tab in the creative inventory whereas normal chests are

The Issue:

Copper chests with different oxidation levels and their waxed variants are included in the “Functional Blocks“ tab but not in the “Redstone Blocks“ tab, whereas normal chests are included in both tabs.

Expected Result:

Since they have similar properties (e.g. can be waterlogged) and basically act the same, I expect them to be sorted in the same way in the creative inventory tabs.

Actual Result:

Variants of copper chests are not included in the “Redstone Blocks“ tab.

Steps to Reproduce:

1. Go into a world.

2. Enter creative mode.

3. Open the inventory and find tabs that contain normal chests and copper chests.
