First preamble paragraph does not have the implicit lead role in the preview

[Vampire]

Observed vs. expected behavior

https://docs.asciidoctor.org/asciidoc/latest/blocks/preamble-and-lead/#preamble-style says that with the default stylesheet the first preamble paragraph gets the implicit lead role if no explicit one is given.

If you generate PDF or HTML from the toolbar this is also done.

But the in-editor preview does not apply this implicit lead role for the first preamble paragraph.

While the "with the default stylesheet" is of course an escape-hatch, it would probably be more consistent to also there use the implicit lead role.

Steps to reproduce

• Have a preamble
• Look at the preview

Thanks for creating this issue. I found the cause, and ask the Asciidoctor project for an update in their stylesheet: asciidoctor/asciidoctor#4564

In the meantime, I'll include a workaround in the plugin, which will be part of the next release. I'll update the issue once a pre-release is available.

The workaround in the plugin will be needed long-term as there's a good reason why the default stylesheet behaves the way it does. See my comment in the linked issue.

Thanks to the Dan's description, I was able to tune the CSS adjustment that it behaves as expected.
