# Description of Changes **What was changed** - Reworked the initial zoom `useEffect`: - Early return when `zoom` is unavailable or initial zoom was already applied. - Extracted an `attemptInitialZoom` function with a single retry path. - Introduced proper timeout handles (`timer`, `retryTimer`) and added a cleanup function to clear them on unmount/re-render. - Expanded the effect dependency array to include `zoomState` to avoid stale state issues. - Switched to nullish coalescing for safer defaulting of `currentZoomLevel` (`zoomState.currentZoomLevel ?? 1.4`). - Minor logging adjustments to clarify delayed/failed initialization paths. **Why the change was made** - The previous implementation risked leaving dangling timers and could re-attempt zoom unnecessarily, causing flicker or inconsistent initial zoom when the viewport wasn’t ready. - Including `zoomState` in dependencies ensures the component reacts to state changes correctly and avoids stale reads. - Cleanup of timers prevents memory leaks and race conditions during rapid mounts/unmounts or navigation. --- ## Checklist ### General - [ ] I have read the [Contribution Guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md) - [ ] I have read the [Stirling-PDF Developer Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/DeveloperGuide.md) (if applicable) - [ ] I have read the [How to add new languages to Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md) (if applicable) - [ ] I have performed a self-review of my own code - [ ] My changes generate no new warnings ### Documentation - [ ] I have updated relevant docs on [Stirling-PDF's doc repo](https://github.com/Stirling-Tools/Stirling-Tools.github.io/blob/main/docs/) (if functionality has heavily changed) - [ ] I have read the section [Add New Translation Tags](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md#add-new-translation-tags) (for new translation tags only) ### UI Changes (if applicable) - [ ] Screenshots or videos demonstrating the UI changes are attached (e.g., as comments or direct attachments in the PR) ### Testing (if applicable) - [ ] I have tested my changes locally.
