Nested list does not work

[cxx7532706]

When I try to use markdown nested list, it doesn't work.
E.g.

* A
  *a
  *b

it shows (it is bullet points, use star to express here)

* A
* a
* b

However, when I check the source code, it looks like normal.

<ul>
<li>A
    <ul>
        <li>a</li>
        <li>b</li>
    </ul>
</li>
</ul>

Does anyone know how to fix this?

There is a blank space between '*' and 'a' 'b' . You can have a try and the following example works well.

* A
    * a
    * b

shows

• A
  • a
  • b
