Closes #8384

Summary

  • Add a Sentry beforeSend filter to drop "frame window is not ready" errors
  • The error originates from third-party scripts or browser internals accessing iframe.contentWindow before the frame is loaded — the exact string does not exist in our source code or any dependency
  • Follows the identical pattern used for the existing non-actionable error filters (dynamic imports, Turnstile, AbortError, invalid origin)

Test plan

  • Verified the error string is not in source code or node_modules (not actionable)
  • Filter follows existing pattern in beforeSend
  • yarn test passes (160 suites, 1550 tests)
  • Post-deploy: monitor Sentry for absence of new "frame window is not ready" errors

🤖 Generated with Claude Code

The "Error: frame window is not ready" is thrown by third-party scripts
or browser internals when accessing iframe.contentWindow before the
frame has finished loading. The error string does not exist in the
source code or any dependency, confirming it originates from external
code. These errors are not actionable and create noise in Sentry.

Closes #8384
