Christian Byrne 1dcd7bca43 docs: add E2E testing gotchas for canvas overlay, context menus, and subgraph navigation (#9951)
Documents 3 hard-learned gotchas from debugging subgraph context menu
E2E tests across ~8 threads:

- Canvas `z-999` overlay intercepting `click()` on DOM widgets → use
`dispatchEvent`
- Context menus requiring node selection before right-click
- Subgraph node sizing minimum for reliable `navigateIntoSubgraph()`

Added to both `browser_tests/AGENTS.md` (auto-loaded for agents working
in that dir) and the Playwright test-writing skill's Common Issues
table.

## Gotchas
| Symptom | Cause | Fix |
| -------------------------------------------------- | ------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
| `subtree intercepts pointer events` on DOM widgets | Canvas `z-999` overlay intercepts `click()` | Use Playwright's `locator.dispatchEvent('contextmenu', { bubbles: true, cancelable: true, button: 2 })` |
| Context menu empty or wrong items | Node not selected | Select node first: `vueNodes.selectNode()` or `nodeRef.click('title')` |
| `navigateIntoSubgraph` timeout | Node too small in test asset JSON | Use node size `[400, 200]` minimum |
## After Making Changes
- Run `pnpm typecheck:browser` after modifying TypeScript files in this directory
- Run `pnpm exec eslint browser_tests/path/to/file.ts` to lint specific files
- Run `pnpm exec oxlint browser_tests/path/to/file.ts` to check with oxlint
## Skill Documentation
A Playwright test-writing skill exists at `.claude/skills/writing-playwright-tests/SKILL.md`.
The skill documents **meta-level guidance only** (gotchas, anti-patterns, decision guides). It does **not** duplicate fixture APIs - agents should read the fixture code directly in `browser_tests/fixtures/`.
