Research direction
Reproduce the crash at the provided Uniswap swap URL using the recorded swap state, browser, and Ropsten chain. Start by tracing the minified stack frames in static/js/35.8c2ca95e.chunk.js and main.ee9b8398.chunk.js back to the swap calculation path. Done means this state no longer throws a division-by-zero error and the affected swap flow remains usable.
