/**
2+
* Bridges TanStack Form state to legacy editor props (values / onChange) while syncing editDraft upward.
3+
*
4+
* ## Do not “fix” by always passing `defaultValues: editDraft`
5+
*
6+
* `useForm` calls `formApi.update(opts)` on every render. If `opts` includes `defaultValues` taken from
7+
* the parent `editDraft` prop, that object can lag the TanStack store by one React frame: after
8+
* `form.reset(next)` from a Chakra `onChange`, `useStore` re-renders this component before
9+
* `setEditDraft` from `listeners.onChange` has committed. `FormApi.update` may then treat parent
10+
* `defaultValues` as the source of truth and overwrite `values` (see `@tanstack/form-core` `FormApi.update`:
11+
* `shouldUpdateValues` when `!isTouched` — legacy inputs are not TanStack `Field`s, so the form often
12+
* stays “untouched”). Result: inputs look broken (e.g. empty “Post ID” / `default_value`).
13+
*
14+
* We pass `defaultValues` only on the **first** options object, then drop it via
15+
* `includeDefaultValuesInOpts` after `useLayoutEffect`, so subsequent `update({ listeners })` calls
16+
* never push a stale `editDraft` snapshot into the store. Remount per field via `key={clientId}` still
17+
* gets a fresh initial `defaultValues` when switching rows.
18+
*
19+
* ## Parent `editDraft` replaced in place (same `clientId`)
20+
*
21+
* After mount we no longer pass `defaultValues` from props, so if the parent replaces `editDraft`
22+
* (undo, server refresh) without remounting, we `form.reset(editDraft)` when a stable serialization of
23+
* the incoming prop differs from the form store. User edits stay in sync because the listener updates
24+
* the parent before the serialized snapshot diverges.
