The reason for this. The reg matched comment script.
And other peopel simiar issues is also the script don't matched .
And other sence isn't rewrite other html files. eg.vuejs/core#1194 it isn't best practice for a spa appliction.Maybe we can add multi entry support it, like webpack entry.
const scriptRE = /(<script\b[^>]*>)([\s\S]*?)<\/script>/gm

I fix this through other way which devFlag + html.

But still has other bugs with the track dependencies.
1.Because maybe matched comment script.
2.Because matched one script tag and tracked one dependencies.

BTW, I find someone of the dependencies of vue is esm-bundler and the vue-next not packaged esm-browser. I'm confused with this, hope get some tips.

#160

I don't know if this is related to #160... or #164. The dev server should have nothing to do with the build. And I have no idea why the scripts are commented out unless there is a reproduction.

[yyx990803]

@underfin now I understand what you mean. I didn't merge #164 because this and #160 are in fact separate problems, and multi-entry support is also more complex since it involves build.

[underfin]

Yeah.I'm sorry for not say it clearly.

I ran into the same problem with svelteKit, on just one specific page.
Can't develop my project without building it hundreds time a day, feels like a stone age.
