Review Comment:
   This fallback now ignores the fullscreen-aware `getPopupContainer` that 
`ChartHolder` supplies through `AntdThemeProvider`, because an explicit 
callback on the Select wins over the provider. In chart fullscreen, a Select 
with no override (e.g. the AG Grid table's `SearchSelectDropdown` "Search by") 
will portal its options to `document.body`, outside the fullscreen element, so 
they won't be visible or clickable. Previously the `parentNode` fallback kept 
them inside. Could the default defer to the provider's container (or keep 
fullscreen containment) before falling back to `document.body`? The same 
applies to `AsyncSelect`.

Review Comment:
   Nothing in the PR exercises this default: the new GroupBy and color-scheme 
tests all pass an explicit popup container, and `popup.closest('body')` would 
also pass for an inline popup. Reverting this (or the `Select.tsx` twin) to 
`triggerNode.parentNode` would bring the double scrollbar back with every test 
green. Could you add a test, parameterized over `Select` and `AsyncSelect`, 
that renders inside a non-modal scrollable wrapper with no `getPopupContainer`, 
opens the dropdown, and asserts the popup's parent is `document.body` and not 
inside the wrapper? `antdDomContract.test.tsx` already covers the modal side.
