When a URL like app.uniswap.org/#//example.org is opened, stripping the '#' leaves '//example.org' which React Router passes to history.replaceState. The browser rejects protocol-relative URLs from a different origin, throwing a SecurityError and showing the error overlay. Only redirect when the resulting path starts with a single '/', which preserves all valid legacy hash routes like #/swap while ignoring external-looking fragments. Fixes Uniswap#7979
