Research direction
Investigate the `uniqueKeys()` method implementation in Dexie.js, likely in the `src/` directory. The bug occurs in Safari when the database is empty, suggesting a browser specific issue with opening cursors. Check how `uniqueKeys()` uses IndexedDB's `openCursor` and whether Safari handles empty stores differently. Review any existing comments in the issue for hints, and test with a minimal reproduction using Safari's WebDriver or local testing.
