A React plugin bundle exports its component by assigning to the shared `globalThis.AirflowPlugin` as a side effect of being imported. When a bundle is malformed or empty and never makes that assignment, the loader read whatever value a *previously-loaded* plugin had left on `globalThis.AirflowPlugin` — so one plugin silently rendered another plugin's component instead of failing. The `typeof !== "function"` guard didn't catch it because the stale value is a valid function. This clears the shared global before each import, so a bundle that assigns nothing surfaces a clear error (and the error page) rather than inheriting a stale component. The resolved component is also cached under its plugin name only after validation, so a failed load never leaves a bad value behind. closes: #56169 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Opus 4.8) Generated-by: Claude Code (Opus 4.8) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
