Description

There is a strange behavior of tile boundaries when the terrain is turned on. If you change the zoom or rotate the camera, tiles change their positions and even 'jump'.

Everything stands still when there is no terrain.
Why is it happening?

mapbox-gl-js version: 2.6.1

Research direction

Start with the linked CodePen demonstration using mapbox-gl-js 2.6.1, enable terrain, and reproduce the boundary jumps while changing zoom and camera rotation. Compare the behavior with terrain disabled; done means tile boundaries remain stable during those camera changes. The payload names no source file or test, so locating the rendering path will require project research.
