Markdown: continue numbered list

In the following markdown code I want item 3 to start with list number 3. But because of the code block in between markdown starts this list item as a new list. Is there any way to prevent that behaviour?

Desired output:

1. item 1
2. item 2

```
Code block
```

3. item 3

Produced output:

1. item 1
2. item 2

Code block

1. item 3

Use four spaces to indent content between bullet points

1. item 1
2. item 2

    ```
    Code block
    ```
3. item 3

Produces:

1. item 1

2. item 2

   Code block

3. item 3

As an extension to existing answers. For those trying to continue a numbered list after something other than a code block. For example a second paragraph. Just indent the second paragraph by at least 1 space.

Markdown:

1. one
2. two

 three
3. four

Output:

1. one

2. two

   three

3. four

Notice how in Macmade's solution, you can see an extra line of code above the "Code block".

Here are two better solutions:

1. Indent the code block by an extra 4 spaces (so usually 8, in this nested list example, 12). This will put the code in a <pre> element. On SO, you can even specify syntax highlight with a
   <!-- language: lang-js --> indented by 4 spaces (+1 here due to the nested list).

   1. item 1

   2. item 2

      Code.block('JavaScript', maybe)?
      

   3. item 3

2. Or, just put the Code block within backticks and indent by 4 spaces (here, 1 extra because of the nested list). You'll get a regular indented text paragraph, with a <code> element inside it. This one you can't syntax-highlight:

   1. item 1

   2. item 2

      Code block

   3. item 3

Macmade's solution doesn't work for me anymore on my Jekyll instance on Github Pages anymore but I found this solution on an issue for the kramdown github repo. For OP's example it would look like this:

1. item 1
2. item 2

```
Code block
```

{:start="3"}
3. item 3
