Four React-19-sensitive patterns that pass on React 18 today but break
under React 19 (verified on the in-flight TanStack Start branch).
Landing on master now so the eventual React 19 upgrade is a no-op for
tests, instead of a separate cleanup pass under upgrade pressure.
Each fix is a strict superset / less-fragile equivalent of the existing
pattern, so master (React 18) stays green.
**Changed:**
- `hooks/misc/useStateTransition.ts` — fire on entry into `newTest` from
any state other than `newTest`, instead of requiring exactly `prevTest →
newTest`. React 18+ auto-batches dispatches across awaits (e.g.
`dispatch SUBMIT` in the handler, `dispatch ERROR` in `onError`),
collapsing `editing → submitting → error` into a single render where the
intermediate `submitting` tick is never observed. Strict superset of the
old check for our reducers — `success`/`error` are only reachable from
`submitting`.
- `Support/CategoryAndSeverityInfo.tsx` — guard `onValueChange` against
Radix Select's spurious `''` emission. When the controlled value
transitions from `undefined` to a defined value whose `SelectItem` isn't
mounted yet (dropdown closed → items haven't registered), Radix's hidden
`BubbleSelect` fires `onValueChange('')` and clobbers the field. No
`SelectItem` can have `value=""` (Radix throws), so any `''` is
guaranteed spurious — drop it before calling `field.onChange`.
([radix-ui/primitives#3381](https://github.com/radix-ui/primitives/issues/3381))
- `EditSecretModal.test.tsx` — `getByLabelText` → `findByLabelText`.
Under React 19's scheduling, the decrypted-value query resolves on a
separate render tick, so form fields appear one tick after the skeleton.
- `LogsPreviewer.test.tsx` — `addEventListener('click', spy)` instead of
`loadOlder.onclick = vi.fn()`. React 19 reassigns `.onclick` on managed
elements as part of its event wiring, clobbering the direct-property
spy.
## To test
### Unit tests
- `pnpm --filter studio test` — all unit tests pass on master (React 18)
### Support form URL prefill (Radix Select guard)
- `/support/new?category=Problem` → category dropdown reads "APIs and
client libraries" on first paint
- `/support/new?category=dashboard_bug` → "Dashboard bug"
(case-insensitive match)
- `/support/new?category=invalid_garbage` → falls back to "Select an
issue" placeholder, no crash
- `/support/new?subject=My%20issue&message=Details%20here` → subject and
message inputs are prefilled
- `/support/new?projectRef=<your-ref>&category=Problem` → both project
selector and category set, library selector appears
- With a prefilled URL, click the category dropdown and pick a different
option — the new value sticks (this is the path that surfaced the Radix
bug, want to confirm we didn't break user selection)
- DevTools console on first load should be clean — no React hydration
mismatch warning
### Support form submit (`useStateTransition` success + error branches)
- Submit a valid support form → green toast "Support request sent"
appears **once**, view swaps to the success screen, one `POST
/platform/feedback/send` in the network panel
- Block `POST /platform/feedback/send` in DevTools → submit → red error
toast appears **once** (not twice — if you see two toasts the relaxed
transition is firing more than it should), form stays editable with all
inputs preserved
- Unblock and submit again → success path runs cleanly
### Sidebar support form (same reducer + `useStateTransition`, separate
component)
- Open the support widget in the side nav (`SupportSidebarForm`)
- Repeat the success and error paths — should behave identically

Refactors our help sidebar within Studio to include the actual support
form itself when contact is selected. This PR also cleans up the initial
state of the sidebar and the options within.
## To test:
- Open an org and click the help icon top right
- Click contact support
- Submit a support ticket
- Click done to return to support sidebar state

* refactor: refactor support form
Refactor support form to make it easier to maintain:
- Split up large components into smaller components and hooks
- Lift state up so we don't have to do complex child/parent
state-syncing via useEffect
- Use nuqs parsing for consistent serialization/deserialization of
support form prefilled fields
* test: support form
Add comprehensive tests for support form
* fix(support form): project and org empty state
* Nit clean up
* More clean up
* cleannnn
* fix(support form): allow case-insensitive category in url
* clean(support form tests): remove unused param
* fix(support form): incorrect logic for sending affected services in payload
* clean(support form): use NO_ORG_MARKER and NO_PROJECT_MARKER instead of strings
* fix(support form): don't show upgrade cta if already on enterprise
