Option to preserve html comments

[jods4]

Is your feature request related to a problem? Please describe.
Removing all comments in HTML files is a bit heavy-handed.

I was trying to port an application that makes uses of Knockout.js to Vite, which uses comments for templating.
In this specific instance, removing <!-- ko: ... --> and <!-- /ko --> comments results in a broken application.

Describe the solution you'd like
An option to configure the regex used to strip comments would be nice, with maybe false meaning don't strip comments at all.

I don't think Vite removes comments from HTML. Can you open a bug report instead?

@yyx990803 Right here:
https://github.com/vitejs/vite/blob/main/packages/vite/src/node/server/middlewares/indexHtml.ts#L19
And there:
https://github.com/vitejs/vite/blob/main/packages/vite/src/node/plugins/html.ts#L41

Oh I thought you were talking about build!
