AsciiDoc table cell styling not functioning in PDF output

Version

$ asciidoctor-pdf -V
Asciidoctor PDF 1.5.0.alpha.11 using Asciidoctor 1.5.4 [http://asciidoctor.org]
Runtime Environment (ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]) (lc:UTF-8 fs:UTF-8 in:- ex:UTF-8)

My Wish

To insert an unordered list in the cell of a table in a PDF file.

The Problem

The table below is a direct copy from the code block example entitled:

Comparing cells using AsciiDoc styles and no AsciiDoc styles

from the asciidoc table cell formatting section of the Asciidoctor Manual.

[cols="2"]
|===

a|This cell is prefixed with an `a` so the following list is rendered with the AsciiDoc list element styles.

* List item 1
* List item 2
* List item 3
|This cell *is not* prefixed with an `a` so the following list is not rendered with the AsciiDoc list element styles.

* List item 1
* List item 2
* List item 3

a|This cell is prefixed with an `a` so the following paragraph is rendered with the `lead` style.

[.lead]
I am a paragraph styled with the lead attribute.
|This cell *is not* prefixed with an `a` so the following paragraph is not rendered with the `lead` style.

[.lead]
I am a paragraph styled with the lead attribute.

When I generate the PDF the end result looks like this:

when it should look like this (screenshot from Asciidoctor manual):

This is a known limitation right now. See #6.

As I mention in #6, what we're going to need to do is implement a custom cell handler in Prawn. That's the only way we'll be able to delegate back into the converter so that the page calculations can be handled by Prawn.
