Placing blocks isn't synched with the player's flying speed

Steps to reproduce:

1. Create a world set to gamemode creative (can be reproduced better on a flat world);
2. Start flying and look down;
3. Sprint and break/place blocks;
4. You'll be too fast for the game to recognize that you're trying to build a line.
5. Flying to the sides will have the same effect, even though you can't sprint in those directions.
