Auto‑jump triggers unexpected jump when sprinting onto fence with solid block behind it

Briefly

When auto‑jump and sprint are enabled, walking towards a fence with a solid block behind it causes an unintended extra jump.

Steps to reproduce

1. Turn on Auto‑jump in settings.

2. Place a fence on ground.

3. Put any full solid block directly behind the fence.

4. Sprint forward toward the fence, keep looking straight ahead.

5. Move onto the fence.

Expected result

Players will get blocked if they go towards the fence, no extra jump.

Actual result

Player performs an unexpected, unnecessary jump when walking towards the fence. This only happens when a solid block exists behind the fence and auto‑jump + sprint are active.
