Research direction

Start by reproducing the swap URL with the supplied swap state and inspect the TypeError stack trace in the bundled JavaScript. The report does not identify a source file or test, so tracing the corresponding frontend code is required before the change can be scoped. Done means this URL no longer crashes when the output currency is set and the empty input state is preserved.
