This is akin to issue MC-259414, but pertains to view bobbing instead of damage tilt. When view bobbing is enabled, your camera moves, yet it doesn't affect your aiming direction, allowing you to target a block that your crosshair isn't directly positioned over. This behavior mirrors what's observed in MC-157877. To replicate, execute the following commands:

/fill ~ ~-1 ~ ~20 ~-1 ~ stone
/execute align xyz run tp @s ~ ~ ~ -90 ~

Then traverse the bridge, and you'll notice how you're aiming at blocks even when your crosshair isn't directly over them.
