Falling block will shift it's x coordinate while falling before appearing in it's correct position, causing a visual discrepancy between the animation and actual block position.
Steps to Reproduce:
Place torch below sand or gravel.
Break block above torch.
Expected Result:
Falling block animation should retain x coordinate.
Actual Result:
Falling block animation will play next to actual block position.
Before anyone asks, yes I play with add-ons and yes I tested if they were causing this - and still occured in a vanilla environment.
