## Summary
This PR reverts #5922 which fixed pointer capture behavior on video and
image preview components to prevent unintended node dragging.
## Changes
- Removes `data-capture-node="true"` attribute from `VideoPreview.vue`
and `ImagePreview.vue` components
- Removes pointer event delegation logic from
`useNodePointerInteractions.ts` composable
- Restores previous drag behavior where dragging on preview components
triggers node drag
## Reason for Revert
This changes the behavior from original Litegraph and is generally
annoying. Users would rather be able to drag the node than be able to
drag an image/video out from a node.

## Summary
Replaced reactive (Vue-based) widget LOD with CSS visibility control.
Performance doesn't dramatically improve, but we avoid the mount/unmount
overhead during zoom/pan operations. This PR implements the visual
component of LOD—complex widgets that need lifecycle management will be
addressed separately.
### Problem & Solution
Problem: we want LOD to improve rendering performance and visual
feedback but discovered using reactivity in the current setup for it
meant mounting/unmounting caused worse lag than the performance it aimed
to fix. Switching to render all the details all the time but using css
visibility proved to be the best solution. However, it doesn't improve
rendering performance by much because the GPU texture size is the
bottleneck (from TransformPane.vue CSS transforms) and not
rasterization.
Solution: Keep all nodes/widgets mounted, use CSS visibility: hidden for
LOD. Trade memory for performance stability during zoom/pan/drag
operations.
### Technical Decision
We chose Performance > Memory:
- CSS transforms create a single GPU texture whose size depends on node
count, not widget complexity
- Mounting/unmounting hundreds of widgets during zoom = noticeable lag
from Vue VDOM diffing (since all components are mounted all the time
because of viewport culling challenge/trade off see
https://github.com/Comfy-Org/ComfyUI_frontend/pull/5510.)
- CSS visibility changes = no reactivity overhead, smooth interactions
- Result: Similar performance, but without interaction stutters
This is the visual layer only. If we want a hook into the LOD state per
node / widget that would be the next follow up system to implement.
### Next Steps (maybe)
- Chunked (split up single Transform Pane transform layer) when
rendering 1000+ nodes (maybe)
- ~~Selective unmounting API for widgets that register as "expensive"~~
- ~~Client bound hydration system~~

* add image outputs on Vue nodes
* add unit tests and update cursor pointer
* use testing pinia
* properly mock i18n in component test
* get node via current graph
* use subgraph ID from node creation
* add better error handling for downloadFile util
* refactor: simplify image preview component architecture
- Replace awkward composable pattern with standard Vue component state
- Fix reactivity issues where images didn't update on new outputs
- Add proper subgraph-aware node resolution using NodeLocatorId
- Enhance accessibility with keyboard navigation and ARIA labels
- Add comprehensive error handling and loading states
- Include PrimeVue Skeleton for better loading UX
- Remove unused composable and test files
The image preview now properly updates when new outputs are generated
and follows standard Vue reactivity patterns.
* resolve merge conflict with main
- Keep both subgraphId field and hasErrors field from main
- No conflicts in other files (LGraphNode.vue and main.json merged cleanly)
* Fix LGraphNode test by adding proper Pinia testing setup
Added createTestingPinia and i18n configuration following the pattern
from working ImagePreview tests. Resolves test failures due to missing
Pinia store dependencies. All 6 tests now pass successfully.
