Nested ordered / unordered list inconsistent behavior

[tiansh]

INPUT:

* aaa
  1. bbb

PERFER:

• aaa
  1. bbb

<ul>
  <li>
    aaa
    <ol>
      <li>
        bbb
      </li>
    </ol>
  </li>
</ul>

but got:

<ul>
  <li>
    aaa
  </li>
</ul>
<ol>
  <li>
    bbb
  </li>
</ol>

According to the documentation, nested elements must have, at least, 4 spaces indentation.

* aaa
   1. bbb

You can check the demo with your example working

[tiansh]

* aaa
  * bbb

* aaa
  1. bbb

But why these two have different behavior?

First one currently been parsed to <ul><li>aaa<ul><li>bbb</li></ul></ul>.
But second one is <ul><li>aaa</li></ul><ol><li>bbb</li></ol>.

You are absolutely right, it's a bug. I will take a look a soon as possible.

Regardless, the 3 space indentation rule should apply to both ordered and unordered lists. They should behave exactly the same.

should be fixed now in latest development

@tivie May I ask why it made more sense to be more restrictive to solve the inconsistency, instead of being less restrictive, and allow a minimum of 2 spaces for mixed lists as well?

This less restrictive syntax doesn't seem to clash with any other syntax. Many people seem to prefer only 2 spaces, which makes sense because it is simpler. Github also allows indentation with 2 spaces.

We are using Showdown in the new WordPress editor, Gutenberg. I tried disableForced4SpacesIndentedSublists, but it doesn't seem to work, and I see it will be removed from v2.
