All standing sign and wall sign blocks do not show up correctly in the chat autocomplete list ID list in Bedrock Edition.

These blocks should use the same icon as the item form of the sign.

Expected Result

The sign icon matches when used in the setblock and give commands.

Observed Result

The sign icon displays the Pale Oak Planks texture when used in the setblock command.

To Reproduce

1. Open a world in the 1.21.50 preview.
2. Enable Cheats.
3. Type "/setblock ~ ~ ~ pale_oak_" in chat.
4. Observe the planks texture appearing over the icons for "pale_oak_standing_sign" and "pale_oak_wall_sign".
5. Clear the chat.
6. Type "/give @s pale_oak_sign"
7. Observe the correct Pale Oak Sign texture.

To Fix

A simple fix can be done by setting the "carried_textures" property of "pale_oak_standing_sign" and "pale_oak_wall_sign" to "pale_oak_sign_carried" in blocks.json.

Define "pale_oak_sign_carried" in terrain_texture.json as the Pale Oak Sign item texture:

This fixes the Pale Oak Sign texture in the setblock autocomplete list, and does not change any other appearances of the block.
