In Minecraft 1.21.4, holding the sprint key, pressing A or D, and finally pressing W would allow the player to sprint. In Minecraft snapshot 25w02a, this no longer occurs; instead, the player must press W first to sprint.

This change makes sprinting feel more sluggish and unresponsive compared to previous versions and feels unintended due to only being removed for one combination of key presses.

This issue is potentially caused by MC-260440, which was fixed in Minecraft snapshot 25w02a when the behavior started occurring.
