PR #61366 (Fix missing translation keys for blocking dependencies in UI (#61314))
- File: airflow-core/src/airflow/ui/src/components/Clear/TaskInstance/ClearTaskInstanceDialog.tsx
- "- Line 66: State initialized to true - Line 186: Checkbox renders checked={preventRunningTask} → checkbox starts checked - Line 231: API sends { prevent_running_task: true } only when state is truthy"
PR #62172 (Add icon support for theme customization)
- File: airflow-core/src/airflow/ui/src/layouts/Nav/Nav.tsx
- "I find one edge case here but that is kind of nit. Feel free to skip this. If only one icon URL is provided (e.g., only icon with no icon_dark_mode), and the user switches to dark mode, the fallback logic at line 112 will use lightIcon for dark mode too. If that fails, it sets `failedLoadingCusto"

- File: airflow-core/src/airflow/ui/src/queries/useBulkDeleteDagRuns.ts
- "nit: The hook is kind of inconsistent here. We could try follow the pattern in useBulkDeleteVariables.ts:31 and useBulkDeleteConnections.tsx:31: - Accept clearSelections as a parameter - Return { error, isPending,"

- "This change still seems unrelated to the i18n fix. Changing the default value of preventRunningTask from true to false alters the behavior of the Clear Task Instance dialog, which is outside the scope of this PR. I'd suggest either reverting this line or splitting it into a separate PR with an expla"
PR #61063 (Add configurable bundle version defaults)
- File: airflow-core/src/airflow/ui/src/components/Clear/Run/ClearRunDialog.tsx
- "useState + useEffect to sync derived state will cause an extra re-render. Use a nullable override pattern instead: keep override as null until the user interacts, then resolve via override ?? defaultValue."
