Strange <!--> comment in prerendered HTML – why is this appearing?

Hey Vike team 👋

I noticed something odd when inspecting the HTML source of my prerendered clinic pages.

In some cases — especially when rendering dynamic sections like prices, locations, or test types — I see a mysterious comment node inside the DOM.

Here’s a screenshot of what I mean:

This only seems to happen when the data is dynamic (fetched from the backend during rendering). I'm using Vike with pre-rendering enabled for all /clinic/[slug] pages.

I'm wondering:

Is this inserted by Vike, or maybe by React during hydration?

Is this expected behavior for hydration boundaries?

Does it affect SEO or performance in any way?

Would appreciate any insights or clarifications you can provide. Thanks a lot for the awesome work!

That's a React thing.
