FIX: Ensure embedded replies/reply-to links open in _blank (PR #14597)

In most cases, these links are handled in JavaScript, so the href and target are not used. However, when the link-to-post refers to a post which is not currently loaded in the DOM (e.g. it is the OP), then the href is used, and we need to add a target to prevent page navigation within the embed iframe.

Is rel="noreferrer noopener" needed here?

I don’t think so - the href will always an ‘internal’ link within the forum domain. We don’t add noreferrer noopener to other internal links in Discourse.
