## Summary
The position of a link relative to its slot was able to drift on load,
due to widgets inside a node being able to resize without triggering an
node-level resize event (min-height node with space at the bottom could
have widgets expand into free space, causing misalignment).
Recreation:
1. Add KSampler
2. Add Float
3. Connect Float to KSamper.denoise
4. Reload workflow (F5)
5. Observe misalignment
## Changes
- **What**:
- track widget grid element as signal only that triggers resync
- node bound calculations skipped for widget signals
- prevent setDirty on non-graph nodes (e.g. LGraphNodePreview)
- tests
## Review Focus
This is a small focused approach to fix the reported issue - it does not
address the underlying issue of the layout not being a SSOT. This fix is
a small bandaid and investigation into resolving the layout SOT issue is
not impacted by this.
