Page summary is null if <!-- more --> is not on a separate line

[maufl]

Bug Report

For some reason the page.summary is always null when the <!-- more --> is not on it's own line. This was working before. I build Zola 0.18 and tested it again and my site still builds with this older version.

Environment

Zola version: 0.19.2

Expected Behavior

When using <!-- more --> in the page content, I would expect page.summary to contain a string.

Current Behavior

page.summary is null if <!-- more --> is preceded by anything else on the same line.

Step to reproduce

Test to reproduce that fails. Add to components/markdown/tests/summary.rs

#[test]
fn summary_matches_at_end_of_line() {
    let rendered = get_rendered(
        r#"
Hello world, with extra content <!-- more -->

More content in next paragraph"#,
    );
    assert!(rendered.summary.is_some());
}

It was due to a change in the markdown library. It's been fixed for inline HTML (#2606) but no markdown it seems

#2581 is still open as a proper fix for this, although it also allows <!-- more --> mid-paragraph which was considered contentious.
