Fixes #13511 by checking whether the world border in question has already been ticked during the current tick.
1.21.11 added some additional lerping logic into
WorldBorder.MovingBorderExtent#update(). Virtual (per-player) world borders are ticked byServerPlayer#tick(), meaning that each player viewing the world border ticks it. In <=1.21.10 this worked fine since there was no logic being done if the lerp was in progress, however, the added logic in .11 causes the server-side lerp speed to multiply based on the amount of players viewing the border.
