Build process hangs at 'modules transformed' with >=2.9.7, works with 2.9.6

Describe the bug

Follow up on #8517 - I missed the auto closing. I created a repro. The problem seems to be coming when using a certain library, but should shed some light on why this is happening in the first place.

The build is eventually finishing, but just takes extremely long. In my actual project it doesn't finish within 10 minutes... As already mentioned, changing this LOC https://github.com/johannes-z/vite2/blob/main/src/main.ts#L22 to the following fixes the issue too. Changing format to es works also - it's just umd that's broken:

baseUrl: getPageContext() ? getPageContext().web.absoluteUrl : window.location.origin

Also happens with vite 3 alpha 14

Reproduction

@johannes-z Would you try #8741? It might fix this issue.
