AI Summary

This patch release improves performance by caching the zoom pane extent and fixes bugs related to dark mode, node positioning, and event handling.

Key Highlights

Cache zoom pane extent to prevent synchronous layout during panning and pinching
Fix dark mode background pattern color
Fix `fitView` behavior with hidden nodes having intrinsic sizes
Fix parent node position clamping to prevent errors
Correct event firing logic for pan/zoom start/end

### Patch Changes

-   [#5850](https://github.com/xyflow/xyflow/pull/5850) [`c707267`](https://github.com/xyflow/xyflow/commit/c707267bc80bc954fdc69a08c9e00c98068dd613) - Cache the zoom pane extent so panning and pinching no longer force a synchronous layout.


-   [#5839](https://github.com/xyflow/xyflow/pull/5839) [`0c0cebc`](https://github.com/xyflow/xyflow/commit/0c0cebc08cc34d2852d1ea429df638732b3edf68) - Use correct fill color for bg pattern in dark mode


-   [#5851](https://github.com/xyflow/xyflow/pull/5851) [`56cf3b0`](https://github.com/xyflow/xyflow/commit/56cf3b00369a680a71743e4fb277db26e861d4b0) - Fix `fitView` with `includeHiddenNodes` ignoring hidden nodes that declare an intrinsic size (`width`/`height`/`initialWidth`/`initialHeight`) but were never measured


-   [#5845](https://github.com/xyflow/xyflow/pull/5845) [`a01bb6b`](https://github.com/xyflow/xyflow/commit/a01bb6bf51e2de4eeee052187f3ce533c0e77754) - Check if parent node is in node lookup before clamp the position to prevent throwing an error.


-   [#5849](https://github.com/xyflow/xyflow/pull/5849) [`9b3f390`](https://github.com/xyflow/xyflow/commit/9b3f390e21c1801832449389b069c4e5a13b4d7f) - Always fire `onPanZoomEnd` when `onPanZoomStart` was fired due to a pan-on-scroll wheel tick


-   [#5837](https://github.com/xyflow/xyflow/pull/5837) [`cdfcbeb`](https://github.com/xyflow/xyflow/commit/cdfcbeb9618437b2e7c35336db157e36a5a0731e) - Check for element existence and type before checking property existence in node/edge typeguards.
