A paragraph after a nested list with a blank run behind its + leaves the outer item

What happens

A nested list whose leading gap carries a blank run behind its +, followed by an indented sibling marker and then a paragraph, loses the paragraph out of the outer item:

* a
** b

+


  ** z

para

Both Asciidoctor Ruby 2.0.26 and @asciidoctor/core 4.0.11 put para inside the outer item a; the plugin prints it outside (a document-level paragraph). Fifteen of a 540-document two-program probe fail this way (five heads x nine runs x twelve tails; 359 binding); identical on main and under both the withholding and the truncating spelling of the item's leading gap (the #184 change), so no leading-gap spelling reaches it. The body is seven lines, outside the depth-5 list-shape product.

Mechanism

Where the paragraph after the nested list lands, not what the gap spells: the reader closes the outer item at the nested list's end and the following paragraph is not attached, where the reference's list-continuation state still attaches it. Stated at the site in separatorBefore's domain paragraph (src/print/list.ts, the #184 change).

#184 (the leading gap), #121, #161 (the depth-5 product's alphabet).

Start in src/print/list.ts at separatorBefore's domain paragraph and trace how the reader closes the outer item after the nested list. Reproduce the seven-line example and run the two-program probe; done means the following paragraph remains inside the outer item, matching Asciidoctor Ruby and @asciidoctor/core.
