Rules using resource.data run twice in Firestore emulator

<!-- DO NOT DELETE validate_template=true template_path=.github/ISSUE_TEMPLATE/bug_report.md --> Rules that use `resource.data` appear to be evaluated twice in the Firestore emulator. The first time always fails with an error, but the second one succeeds and allows/denies access as expected. This feels similar to #4325, but doesn't involve the use of `onSnapshot` (although I observed the same issue when using `onSnapshot` instead of `getDoc`). Everything appears correct from the client side - the code doesn't appear to run twice, nor are any errors returned from the request. My rules using `resource.data` appear to work correctly when deployed to Firebase and don't show any errors in the Firebase console. <!-- Thank you for contributing to the Firebase community!
