This zoom level can be obtained by changing URL query parameters to e.g. &zoom=-200. Zoom should instead be clamped so that such freezes cannot happen.

The freeze occurs in CanvasRenderer.#collectChunksThisFrame, which iterates over all chunks in the viewport and collects them for rendering. Iterating over such an absurd amount of chunks is bound to cause problems no matter how you look at it.
