- Wheel zoom and pan on middle-click stopped working due to recent
changes in Node's graph canvas container.
- Implement capture-phase wheel event handling on the document to
regain control of preview zoom independent of Node version.
- Add safety checks against zero-size or detached canvases.
- Ensure pointer events reach preview canvases even if parent
containers have pointer-events:none applied.
- Improve compatibility with Node 2.0 by adding fallbacks for
widgets without proper addDOMWidget support.
