Recently, all in-game ui (or container) transparent background opacity has been changed to be more transparent, these changes creates parity issues, as on Java Edition all in-game/container ui has a much darker transparent background.

Affected UI:

• Anvil
• Barrel
• Beacon
• Blast furnace
• Book
• Brewing stand
• Cartography table
• Chest (Small chest, Large chest, Ender chest)
• Command Block
• Crafter
• Crafting table
• Dispenser
• Dropper
• Emote wheel
• Enchantment table
• Furnace
• Grindstone
• Hopper
• Loom
• Mob Effect
• Player Inventory
• Shulker box
• Sign/Hanging Sign
• Smoker
• Smithing table
• Stonecutter
• Trading

Steps to reproduce:

1. Open Minecraft: Bedrock Edition and Minecraft: Java Edition
2. Load into any world
3. Set the time to day: /time set day
4. Open inventory on both games
5. Observe

Expected results:
Both game has the same transparent background opacity.

Observed results:
Minecraft: Bedrock Edition has a more transparent background than Java Edition.

Note:
Entity Inventory (like Horse, Camel, etc) has the same transparent background opacity on both games and are unaffected by this issue.
