Vector Tiles Flickering Artefact

What happened?

There are some flickering when rendering large vector tiles data, which noticeable on our newly released river data sandcastle, as if some tiles suddenly decide to refine from the root or fail to display when zooming.

Potentially related to the vector tiles traversal changes we made recently.

Video captured by @hamburger-earmuffs when creating a video for media post. @danielzhong also identified the issue when trying to create a live demo.
