Review Comment:
   **Suggestion:** The provider is invoked eagerly during `ChatbotMount` 
render, so if an extension's provider function itself throws, the exception is 
raised before `ErrorBoundary` can mount and it will bubble up to the host 
render tree. Render the provider as a child component boundary target (instead 
of calling it inline) so provider-level failures are actually isolated. 
[possible bug]

   ```mdx
   - ❌ Misbehaving chatbot provider can crash ChatbotMount host render.
   - ⚠️ Undermines intended isolation tested in ChatbotMount tests.
   ```
   </details>
   <details>
   <summary><b>Steps of Reproduction ✅ </b></summary>
   
   ```mdx
   1. In `superset-frontend/src/components/ChatbotMount/ChatbotMount.test.tsx`, 
add a new
   test similar to `isolates a failing chatbot so it does not crash the host` 
(lines 77–90)
   but with a provider that throws synchronously instead of a child component:
   
      `const provider = () => { throw new Error('chatbot blew up'); };` 
registered via
      `views.registerView` as shown in lines 54–63.
   
   2. In that new test, call `render(<ChatbotMount />);` as done in existing 
tests at
   `ChatbotMount.test.tsx:33`, `48`, and `71`, which mounts `ChatbotMount` from
   `superset-frontend/src/components/ChatbotMount/index.tsx`.
   
   3. During initial render of `ChatbotMount` (file `index.tsx` lines 29–82),
   `getActiveChatbot` from `superset-frontend/src/core/chatbot/index.ts:59–86` 
resolves the
   active chatbot and returns its `provider: () => ReactElement`, which is 
stored in
   `activeChatbot` state at lines 33–35.
   
   4. Still in the same render pass, React evaluates the JSX at `index.tsx:79`, 
executing
   `activeChatbot.provider()` inline inside
   `<ErrorBoundary>{activeChatbot.provider()}</ErrorBoundary>`. Because the 
provider throws
   before returning a React element, the exception occurs while rendering 
`ChatbotMount`
   itself (a parent), not a descendant, so the `ErrorBoundary` from
   `src/components/ErrorBoundary` never sees it; the `render(<ChatbotMount />)` 
call in the
   test will throw, demonstrating that a misbehaving chatbot provider can crash 
the host
   despite the intended isolation.
   ```

Review Comment:
   **Suggestion:** The mount resolves and renders a chatbot immediately with 
`null` admin settings, then later replaces it after the async settings fetch; 
with multiple registered chatbots this can show the wrong (non-admin-selected 
or disabled) chatbot briefly. Defer initial resolution until settings load (or 
an explicit "settings unavailable" fallback decision) to avoid rendering an 
incorrect active chatbot. [logic error]
   
   <details>
   <summary><b>Severity Level:</b> Major ⚠️</summary>
   
   ```mdx
   - ⚠️ Chatbot mount can briefly show admin-disabled chatbot.
   - ⚠️ Admin-selected chatbot not honored during initial page paint.
   ```
   </details>
   <details>
   <summary><b>Steps of Reproduction ✅ </b></summary>
   
   ```mdx
   1. Register two chatbot views using the public views API, following the 
pattern in
   `superset-frontend/src/components/ChatbotMount/ChatbotMount.test.tsx:54–63` 
where
   `views.registerView` from `superset-frontend/src/core/views/index.ts:24–44` 
is called
   twice with ids `'first.chatbot'` and `'second.chatbot'` at 
`CHATBOT_LOCATION` from
   `src/views/contributions.ts:25–31`.
   
   2. Configure the backend (or a test mock of `SupersetClient.get` imported at
   `ChatbotMount/index.tsx:20`) so that the `/api/v1/extensions/settings` 
endpoint returns
   `json.result.active_chatbot_id === 'second.chatbot'` and 
`json.result.enabled === {
   'first.chatbot': false, 'second.chatbot': true }`, matching the shape read in
   `index.tsx:42–43`.
   
   3. Render `<ChatbotMount />` as in `ChatbotMount.test.tsx:33/48/71`. Before 
the async
   settings fetch resolves, the `useState` initializer at `index.tsx:33–35` 
calls
   `getActiveChatbot(null, {})`, which delegates to `getActiveChatbot` in
   `superset-frontend/src/core/chatbot/index.ts:59–86`. With `adminSelectedId` 
undefined and
   an empty `enabledMap`, `getActiveChatbot` does not respect the 
admin-selected id or
   disabled flags and simply picks the first registered id (`candidates[0]` at 
lines 76–79),
   so the UI initially renders the first chatbot even though it is disabled and 
not
   admin-selected.
   
   4. Once `SupersetClient.get` resolves in the effect at 
`ChatbotMount/index.tsx:37–47`, the
   component updates `adminSelectedId` and `enabledMap` state and recomputes
   `setActiveChatbot(getActiveChatbot(id, enabled))`, now correctly resolving
   `'second.chatbot'`. This causes `ChatbotMount` to switch from the first 
chatbot's UI to
   the second, demonstrating a brief period where the wrong (disabled or 
non-admin-selected)
   chatbot is rendered before settings load.
   ```
