Research direction

Open https://app.uniswap.org/#/vote and reproduce the crash using the reported Chrome and Windows environment. Use the stack trace in the generated JavaScript chunks to locate the corresponding source entry point and identify the undefined value before split is called. Done means the vote page loads without this TypeError and the regression is covered by an appropriate test.
