Unable to Replace a Single Block by Clicking Both Left and Right Button Simultaneously

Steps to reproduce:

• Create a world of any type.

• Replace a block with the block in your main hand, by clicking left button + right button of your mouse at the same time.

Expected:

Previously, you can replace that original block with the block you’re holding.

Actually:

Actions are not synchronized. Either your block is simply placed, or that original block is broke.
