The interface of Loom and Grindstone doesn't match Java Edition

The interface of Loom and Grindstone doesn't match Java Edition.

LOOM:

In Java, there is a pattern behind input slots. But in Bedrock, there's nothing and the position of the input slot is different to Java. 

GRINDSTONE:

In Java, there is a pattern looks like Grindstone behind input slots. But in Bedrock, you will see nothing behind them.

Others:

It's easy to fix for creators. But I only finished Grindstone's GUI.

I don't know how to make Pocket UI.
