If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

I'm trying to split my middlewares across multiple files, but HMR stops working for the files in src/middleware/. It works as expected for src/middleware.ts, but that also stops working if it is moved to src/middleware/index.ts.
Smells like a similar issue as the one with actions, unless I'm misinterpreting.

What's the expected result?

Files in the src/middleware/ should also trigger HMR.
