Summary:
This test was causing uncaught promise rejections, because the mocked `symbolicateStackTrace` in this test returns a different type from the real one, causing `LogBoxSymbolication`'s unawaited, cached promises to reject.
This wasn't picked up as a test failure because our `promise` polyfill silently swallows uncaught rejections, but it does cause a failure if we use native promises in tests.
Changelog:
[Internal][Fixed] - Fix LogBoxSymbolication-test.js
