Missing/broken sourcemaps for JS modules w/ imports when used with Vue and Vue files

[amirhadar]

Describe the bug

I am puting a breakpoint on a javascript source file with import and the debugger (VSCode) opens the remote file instead of the local file.
If I put a breakpoint on a javascript source file without imports, everything works fine.
If I put a breakpoint on a vue file, all hell break loos.

looks like the return of
#7767

Here is the reproduction:
Doesnt Work Example - javascript file with imports:

remote file opened.

Not Working Example - vue files

Working Example - javascript file without imports:

local file opened

Reproduction

https://github.com/amirhadar/vite_sourcemap_issue

Steps to reproduce

In VSCode

• using Edge Extension
• generate launch

put a breakpoint on a js or vue file and refreash the browser.

• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

The PR (#14247) that fixed #7767 is not included in 4.5.0. It's included in 5.0.0 beta.

[amirhadar]

Thanks for the clarification.

I hope 5.0.0 will arrive soon.
