Sprinting on the edges of blocks causes sprint particles to be created in midair

Relates to MC-262424 and MCPE-18063.

The bug

When falling from a height onto the edge of a block, the particles created will appear at the very edge of the block the player collided with. However, sprinting on the edges of blocks will create the particles under the player, which in many cas3s causes them to be created in midair.

How to reproduce

1. Walk to the edge of a block so you're centered above air but still colliding with the block
2. Sprint parallel to the edge

Expected results

The sprint particles would be always created above the block being collided with.

Actual results

Some are spawned completely in midair.
