Support for Intl.supportedValuesOf?

[kyllerss]

Perhaps I'm looking in the wrong place, but in VSCode (using the Svelte extension - v108.1.0) I'm getting a warning when I use Intl.supportedValuesOf stating that supportedValuesOf it is not part of Intl.

This feature is fully supported by all major browsers.

I made sure to set VSCode's Typescript support to ESNext, but that doesn't seem to make any difference. A similar issue was reported to VSCode's team, but they said it was the responsibility of the extension owner.

I so I guess my question is, has anyone run into this issue and is the right place to fix this at the Svelte VSCode extension? Any tips on how to make the warning go away?
