fix(escapeHtmlComment): Avoid throwing errors due to src not being a …

[lazytong-tech]

When building my project, Vue threw the error src. replace is not a function. After adding toString() to the function escapeHtmlComment, this error did not occur again

Are you able to provide a reproduction of the problem?

I don't think this can be merged until we understand the underlying reason why a non-string was passed to this function.

It reminds me of #8870, which turned out to be caused by UnoCSS incorrectly rewriting Vue code.

When I use the nuxt3 framework and webpack5 as a builder, using unplugin-auto import/webpack and unplugin-vue components/webpack will result in a TypeError: src. replace is not a function error during server-side rendering.
Here is the error message:

$ node .output/server/index.mjs

After changing

function escapeHtmlComment(src) {
  return src.replace(commentStripRE, "");
}

in @vue/shared dist/shared.cjs.prod.js to

function escapeHtmlComment(src) {
  return src.toString().replace(commentStripRE, "");
}

, the error no longer occurs.
