Steps to reproduce

As noted in https://github.com/mdx-js/mdx-analyzer/issues/451#issuecomment-2196432076, the IntelliSense entries for auto-import of React components in .tsx files (auto-import in an .mdx file) are missing.

Clone the reproduction at https://github.com/karlhorky/repro-mdx-analyzer-missing-auto-import-intellisense
Install the 2 recommended extensions unifiedjs.vscode-mdx@1.8.9 and viijay-kr.react-ts-css@3.2.0 (both enabled)
In app/message.mdx, move the cursor to the end ZoomImage and trigger IntelliSense with ctrl-space
Observe one entry in IntelliSense
Select this entry
Observe the import is added at the end of the file
Disable viijay-kr.react-ts-css@3.2.0
Move the cursor to the end ZoomImage and trigger IntelliSense with ctrl-space
Observe zero entries in IntelliSense

Expected behavior

One entry in the IntelliSense for ZoomImage when only unifiedjs.vscode-mdx@1.8.9 installed
Selecting the entry should add the new import to the top of the code (also when viijay-kr.react-ts-css@3.2.0 enabled)
1. Saving the file with an import not in the import block at the top should move the import to the top of the file

Actual behavior

Zero entries in the IntelliSense for ZoomImage when only unifiedjs.vscode-mdx@1.8.9 installed
(when viijay-kr.react-ts-css@3.2.0 enabled) selecting the entry adds the new import to the bottom of the code
1. Saving the file has no effect
