Problem

I'm trying to write a verse with the delimited block syntax. However, this breaks syntax highlight for all content beneath the block. Problem shown below, reproduce by copying provided AsciiDoc into a new file. It breaks without the sidebar code too.

Related to https://github.com/asciidoctor/asciidoctor-vscode/issues/686 but in this case we might be able to do a fix by updating the grammar.
