Works as expected

Dynamically importing TypeScript works just fine:

import("./tsfile").then(console.log);

Dynamically importing JS with a variable also works just fine:

const dynamicjsfile = "mydynamicjsfile";
import("./" + mydynamicjsfile + ".js").then(console.log);

Unexpected behaviour

For some reason importing a ts file dynamically using no file extension (which does work in the rest of the codebase thanks to vite-plugin-dynamic-import) requests exactly that file without transpiling it:

const dynamictsfile = "dynamictsfile";
import("./" + dynamictsfile).then(console.log);

It throws:

Error [ERR_MODULE_NOT_FOUND]: Cannot find module './dynamictsfile' imported from index.bundled_t18m7musuj.mjs

And adding the file-extension to adhere to the vite standard (relative, no alias, file-extension) vite/features#dynamic-import

const dynamictsfile = "dynamictsfile";
import("./" + dynamictsfile + ".ts").then(console.log);

results in forwarding it to esm without transpilation:

node:internal/modules/esm/get_format:176
  throw new ERR_UNKNOWN_FILE_EXTENSION(ext, filepath);     
        ^

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for ./dynamictsfile.ts

}

Using glob import vite/features#glob-import

const modules = import.meta.glob('./*.js')
console.log(modules);

results in:

Unhandled Rejection at: Promise {
  <rejected> TypeError: (intermediate value).glob is not a 
function

reason: TypeError: (intermediate value).glob is not a function

So glob is probably not available in this stage of the compilation process / inside the compile-time context.

I hope I didn't miss something obvious & you can provide some assistance on resolving this issue.
If you need any more info I'd be happy to provide anything you need.

Thanks for your time & this awesome project!
