All of the issues with reflow, layout invalidation, forced layout on property access, recalculating styles, which require careful solutions like batching change operations and optimized rendering strategies, will also affect anything operating on the DOM via WASM. The point stands; maybe a faster VDOM can be built in a compile-to-wasm language, though the bottleneck will remain the browser's DOM API and rendering, not the language interpreter.
