Affected versions:
1.5.0, 1.5.1, 1.5.2, 1.5.3

Summary: When planting crops in a straight line - left/right or forward/backward - every 3rd, 4th, or 5th planting will be skipped.

Steps to Reproduce:
1) Create a line of tilled farmland at least 20 blocks long
2) Put wheat, carrots, potatoes, etc. in hand
3) Walk down the line (either moving sideways or walking backward) and hold the left trigger

Observed Results: Every 3rd, 4th, or 5th planting will be skipped; planting will continue after each skipped block

Expected Results: Every block is planted

Screenshots/Videos Attached: Yes

Notes: Also affects placing of fences (or at least cobblestone fences; I did not test every variety). It seems like this is almost certainly caused by the planting animation taking longer than it takes Steve to walk across a block. Steve walks across 4 blocks in the time it takes the planting animation to plant 3 blocks (or thereabouts), so 1 block is skipped.
