How to markdown nested list items in Bitbucket?

I'm trying to see my markdown nested list items rendered with corresponding indentation when viewed in a browser live from the Bitbucket pages. But I can't figure out how it works even when using their examples (updated):

* Item 1
* Item 2
* Item 3
  * Item 3a
  * Item 3b
  * Item 3c

It ignores indentation for items 3a-c:

I want it to look like this (syntax works perfectly fine on SE and Github):

Their list in list example is particularly unacceptable:

1. Step 1
2. Step 2
3. Step 3
   * Item 3a
   * Item 3b
   * Item 3c

Here's a repo I set up just for this.

Use 4 spaces.

# Unordered list

* Item 1
* Item 2
* Item 3
    * Item 3a
    * Item 3b
    * Item 3c

# Ordered list

1. Step 1
2. Step 2
3. Step 3
    1. Step 3.1
    2. Step 3.2
    3. Step 3.3

# List in list

1. Step 1
2. Step 2
3. Step 3
    * Item 3a
    * Item 3b
    * Item 3c

Here's a screenshot from that updated repo:

Thanks @Waylan, your comment was exactly right.

Possibilities

• It is possible to nest a bulleted-unnumbered list into a higher numbered list.
• But in the bulleted-unnumbered list the automatically numbered list will not start: Its is not supported.
• To start a new numbered list after a bulleted-unnumbered one, put a piece of text between them, or a subtitle: A new numbered list cannot start just behind the bulleted: The interpreter will not start the numbering.

In practice

1. Dog
2. German Shepherd - with only a single space ahead. 2. Belgian Shepherd - max 4 spaces ahead.

• Number in front of a line interpreted as a "numbering bullet", so making the indentation. * ..and ignores the written digit: Places/generates its own, in compliance with the structure. * So it is OK to use only just "1" ones, to get your numbered list. * Or whatever integer number, even of more digits: The list numbering will continue by increment ++1. * However, the first item in the numbered list will be kept, so the first leading will usually be the number "1".
  1. Malinois - 5 spaces makes 3rd level already.
     1. MalinoisB - 5 spaces makes 3rd level already.
     2. Groenendael - 8 spaces makes 3rd level yet too.
     3. Tervuren - 9 spaces for 4th level - Intentionaly started by "55".
     4. TervurenB - numbered by "88", in the source code.

87. Cat
88. Siberian; a. SiberianA - problem reproduced: Letters (i.e. "a" here) not recognized by the interpreter as "numbering".

• No matter, that it is indented to its separated line in its source code: The indentation is ignored here. 2. Siamese
• a. so written manually as a workaround misusing bullets, unnumbered list.

4 spaces do the trick even inside definition list:

Endpoint
: `/listAgencies`

Method
: `GET`

Arguments
:   * `level` - bla-bla.
    * `withDisabled` - should we include disabled `AGENT`s.
    * `userId` - bla-bla.

I am documenting API using BitBucket Wiki and Markdown proprietary extension for definition list is most pleasing (MD's table syntax is awful, imaging multiline and embedding requirements...).

This worked for me in Bitbucket Cloud.

Entering this:

* item a
* item b
** item b1
** item b2
* item3

I've got this:

Even a single space works

>`Nested lists, deeper levels: ---- leave here an empty row

• first level A item - no space in front the bullet character
• second level Aa item - 1 space is enough
  • third level Aaa item - 5 spaces min
  • second level Ab item - 4 spaces possible too
• first level B item`

Nested lists, deeper levels:

• first level A item - no space in front the bullet character

• second level Aa item - 1 space is enough

  • third level Aaa item - 5 spaces min
  • second level Ab item - 4 spaces possible too

• first level B item

    Nested lists, deeper levels:
     ...Skip a line and indent eight spaces. (as said in the editor-help, just on this page)
    * first level A item - no space in front the bullet character
     * second level Aa item - 1 space is enough
         * third level Aaa item - 5 spaces min
        * second level Ab item - 4 spaces possible too
    * first level B item
