## What
12 regression tests covering 10 workflow persistence bug gaps, including
the **critical data corruption fix in PR #9531** (pythongosssss) which
previously had ZERO test coverage.
## Why
Deep scan of 37 workflow persistence bugs found 12 E2E-testable gaps
with no regression tests. Workflow persistence is a core reliability
concern — data corruption bugs are the highest risk category.
## Tests
### 🔴 Critical

state |
### 🟡 Medium

### 🟢 Low
| Bug | PR/Commit | Tests | Description |
|-----|-----------|-------|-------------|
| Locale break | #8963 | 1 | Locale change breaks workflows |
| Panel drift | — | 1 | Splitter panel size drift |
## Conventions
- All tests use Vue nodes + new menu enabled
- Each test documents which PR/commit it regresses
- Proper waits (no sleeps)
- Screenshots scoped to relevant elements
- Tests read like user stories
## 🎉 Shoutout
PR #9531 by @pythongosssss was a critical data corruption fix that now
has regression test coverage for the first time.

## Summary
- When a media node (LoadImage/LoadAudio/LoadVideo) is selected and the
clipboard contains stale node metadata from a prior Ctrl+C, pasting
skips the node-metadata deserialization so that the paste falls through
to litegraph's default handler instead of incorrectly pasting the old
copied node.
- FixesComfy-Org/ComfyUI#12896
## Root Cause
The paste handler in `usePaste.ts` checks clipboard `text/html` for
`data-metadata` (serialized node data) **before** falling through to
litegraph's default paste. When a user copies a node, then copies a web
image, the browser clipboard may retain the old `data-metadata` in
`text/html` while the image data is not available as a
`DataTransferItem` file. This causes the stale node to be pasted instead
of the image.
## Fix
Skip `pasteClipboardItems()` when a media node is selected, allowing the
paste to fall through to litegraph's default handler which can handle
the clipboard content appropriately.
## Test plan
- [x] Added unit test verifying node metadata paste is skipped when
media node is selected
- [x] Manual: Copy a node → copy a web image → select LoadImage node →
Ctrl+V → verify image is pasted, not the node

* move subgraph test assets into subfolder
* [refactor] Organize browser test assets into logical folders
Reorganized test assets for better maintainability:
- groupnodes/: GroupNode feature tests
- groups/: Visual grouping tests
- missing/: Missing nodes/models tests
- links/: Link-related tests
- inputs/: Input widget tests
- widgets/: Widget-specific tests
- nodes/: Node-related tests
