If I create Code Blocks inside a unordered list entry the final rendering is shifted while in the preview everything is ok.

Steps To Reproduce

Create new site with content:

test
```
test
```

Thanks for reporting @sirrrich.

Can confirm this. Seems to be when the proceeding code block whitespace is done with tabs. Using spaces results in a working output.

Tabs produces a different, yet non-malformed as desired, output on the commonmark playground: https://spec.commonmark.org//dingus/?text=-%20test%0A%0A%09%60%60%60%0A%09test%0A%09%60%60%60

Ideally will need to find some time to confirm this and look to fix upstream within https://github.com/thephpleague/commonmark.
