Description

When a code block is placed inside a tab, indents in the code block are all removed.

As a consequence of this, I cannot present a tab structure where one tab is the code snippet, and the other is it running. That means this is impossible:

::: tabs
== tab Code
```html
<div>
    (stuff!)
</div>
```
== tab View
<div>
    (stuff!)
</div>
:::

Steps to Reproduce

✅ Reproducible locally.
✅ Reproducible in the live editor.

Put this snippet in a DocMD page:

::: tabs
== tab Tab
Normal prose

```html
<div>
    <div>
        <div>deepest</div>
    </div>
</div>
```
:::

Expected Behavior

Indents should be left intact.
