On iOS WebKit, migrateFilesStore ran an openCursor() walk inside onupgradeneeded for every oldVersion below 9 - including a brand-new empty database at oldVersion 0. WebKit throws "Attempt to open a cursor in database without an in-progress transaction" once the versionchange transaction goes inactive, and the throw escaped the handler uncaught, so the stirling-pdf-files database never opened and file persistence stopped for that session. Skip the walk when the files store was just created (nothing to migrate), and wrap openCursor(), update(), and continue() so a dead transaction aborts the upgrade cleanly instead of throwing into the void. Apply the same guard to the two cursor walks in fileStorage so they reject their promise rather than escape. Generated-By: PostHog Desktop Task-Id: 4ca1aa52-9e02-4641-8e7e-2f906e36b78b
