Weird error when sourcemap is enabled

[neilfranci]

Describe the bug

When I update from 0.14.7 to 0.15.0 source map is enabled by default and
whenever I make change in content script and save it print the error
Error when using sourcemap for reporting an error: Can't resolve original location of error.

Set it off sourcemap: false will not cause it anymore.

Not sure if this happened with other frameworks like React or Svelte

Thanks for the report. But yeah, not sure TBH. This is the second problem with the vue plugin, also see #270. I haven't had time to look into this in-depth yet, only enough to follow your reproproduction and see the error myself.... Re-running the dev command works, but that's obviously not a solution...

I'll have to explore the vue plugin a bit more to try to figure out what's going on, but I have other priorities right now, so it'd be a great help if someone else helped out with this.
