:lax_spacing with lists

[firien]

This renders OK (using v3):

require 'redcarpet'
md = %{
this is an **unordered** list:

* an item
* another item

this is an **ordered** list:

1. first
2. second

coda
}

renderer = Redcarpet::Markdown.new(Redcarpet::Render::HTML.new)
puts renderer.render md

but trim some newlines and use the lax_spacing option and the second list is wrapped in a <p> tag:
update: GitHub also renders the second list in a <p> tag

md = %{
this is an **unordered** list:
* an item
* another item

this is an **ordered** list:
1. first
2. second

coda
}

renderer = Redcarpet::Markdown.new(
  Redcarpet::Render::HTML.new,
  lax_spacing: true
)
puts renderer.render md
=begin
<p>this is an <strong>unordered</strong> list:</p>

<ul>
<li>an item</li>
<li>another item</li>
</ul>

<p>this is an <strong>ordered</strong> list:
1. first
2. second</p>

<p>coda</p>
=end

pad the numbered list with leading spaces and it renders OK again, is this how it is supposed to work?

md = %{
this is an **unordered** list:
* an item
* another item

this is an **ordered** list:
 1. first
 2. second

coda
}

renderer = Redcarpet::Markdown.new(
  Redcarpet::Render::HTML.new,
  lax_spacing: true
)
puts renderer.render md
=begin
<p>this is an <strong>unordered</strong> list:</p>

<ul>
<li>an item</li>
<li>another item</li>
</ul>

<p>this is an <strong>ordered</strong> list:</p>

<ol>
<li>first</li>
<li>second</li>
</ol>

<p>coda</p>
=end
