is it okay to set meta tags in onMount?

Describe the bug

This is more of a question than a bug. Right now, we are setting the title and description during onMount which will run after hydration (in client side).

Don't you think it defeats the purpose of SEO? since it won't be available in the server rendered HTML. Correct me if I am wrong.

Bump, this is a very good question

The Seo component exports the meta tag values as props, like:

export let title: string;
export let description: string;

It allows to update, say the title, using a store. When we have more data to fill that component (a page title, description, and card info (title, image)) we should add them as props.
