Test 1

  1. foo

     1. bar

     2. baz

  2. lorem

  ipsum

Ownership

This table is just showing ownership for the plain list items, not the containing plain list nor the elements inside each item.

Plain List Item	Owns trailing blank lines
foo (includes bar baz)	Yes
bar	Yes
baz	Yes
lorem	No

Analysis

In this test case, we see that the only list item that doesn't own its trailing blank lines is "lorem", the final list item of the outer-most list.

Test 2

We add "cat" as a paragraph at the end of foo which makes "baz" lose its trailing blank lines.

Source

  1. foo

     1. bar

     2. baz

     cat

  2. lorem

  ipsum

Ownership

Plain List Item	Owns trailing blank lines
foo -> cat (includes bar baz)	Yes
bar	Yes
baz	No
lorem	No

Analysis

In isolation, this implies that the final plain list item does not own its trailing blank lines, which conflicts with "baz" from test 1.

New theory: List items own their trailing blank lines unless they are both the final list item and not the final element of a list item.

Plain List Item	Owns trailing blank lines	Why
foo -> cat (includes bar baz)	Yes	Not the final list item
bar	Yes	Not the final list item
baz	No	Final item of bar->baz and not the final element of "foo"
lorem	No	Final item of foo->lorem and not contained in a list item

Test 3

So if that theory is true, taking the entire (foo -> lorem) list from test 1 and nesting it inside a list should coerce "lorem" to own its trailing blank lines since it would then be a final list item (of foo -> lorem) and the final element of the new list.

Source

  1. cat
     1. foo

        1. bar

        2. baz

     2. lorem

  ipsum

Ownership

Plain List Item	Owns trailing blank lines
cat (includes foo -> lorem)	No
foo (includes bar baz)	Yes
bar	Yes
baz	Yes
lorem	No

Analysis

Against expectations, we did not coerce lorem to consume its trailing blank lines. What is different between "baz" and "lorem"? Well, "baz" is contained within "foo" which has a "lorem" after it, whereas "lorem" is contained within "cat" which does not have any list items after it.

New theory: List items own their trailing blank lines unless they are both the final list item and not the final element of a non-final list item.

Plain List Item	Owns trailing blank lines	Why
cat (includes foo -> lorem)	No	Final list item and not contained in a list item
foo (includes bar baz)	Yes	Not the final list item
bar	Yes	Not the final list item
baz	Yes	Final element of non-final list item
lorem	No	Final list item and final element of final list item

Test 4

So if that theory is true, then we should be able to coerce lorem to consume its trailing blank lines by adding a second item to the cat list.

  1. cat
     1. foo

        1. bar

        2. baz

     2. lorem

  2. dog

Ownership

Plain List Item	Owns trailing blank lines
cat (includes foo -> lorem)	Yes
foo (includes bar baz)	Yes
bar	Yes
baz	Yes
lorem	Yes
dog	No

Analysis

For the first time our expectations were met!

Enduring theory: List items own their trailing blank lines unless they are both the final list item and not the final element of a non-final list item.

Plain List Item	Owns trailing blank lines	Why
cat (includes foo -> lorem)	Yes	Not the final list item
foo (includes bar baz)	Yes	Not the final list item
bar	Yes	Not the final list item
baz	Yes	Final element of non-final list item
lorem	Yes	Final element of non-final list item
dog	No	Final list item and not contained in a list item
