vscode extension fails with new refactoring "move to file"

[SantoJambit]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Affected packages and versions

1.8.2

Link to runnable example

No response

Steps to reproduce

• Install the extension
• create an .mdx file and two .ts files
• try to move something from one ts file to another via the new refactoring "move to file"
• observe the error shown by vscode

Expected behavior

vscode should show the file selection popup (it does without the extension installed)

Actual behavior

An error pops up:

TypeScript Server Error (5.4.2)
Debug Failure. File /.../file.mdx has unknown extension.

Hi! This was marked as ready to be worked on! Note that while this is ready to be worked on, nothing is said about priority: it may take a while for this to be solved.

Is this something you can and want to work on?

Team: please use the area/* (to describe the scope of the change), platform/* (if this is related to a specific one), and semver/* and type/* labels to annotate this. If this is first-timers friendly, add good first issue and if this could use help, add help wanted.

This is also a debug error encountered by @Princesseuh in astro language tools. It needs to be solved upstream. I will open an issue to TypeScript.

Yep, here's the corresponding issue withastro/astro#14667 in Astro

This is somewhat relevant to withastro/language-tools#413 - downgrading to 1.7.3 worked

See my extension list - I do not have astro tool:
