Start by reproducing the crash from the reported swap URL and inspect the minified stack entry at static/js/35.d35d34a0.chunk.js, especially getCachedUrl. Trace how the application accesses localStorage when browser access is denied; done means the swap page no longer crashes in that condition and the reported error is covered by a regression test.
