code block issue in discourse

Here's a code block below showing how to do code blocks. It works

    ```JavaScript
    function some(JavaScript, "code") {}
    ```

Then here's the same code block without the indent. That works too

```JavaScript
function some(JavaScript, "code") {}
```

Then here's another code block with an indent. It is not working in fact it's showing up directly inline in this paragraph for some reason

    ```
    function some(JavaScript, "code");
    ```

And finally another unindented code block half works (not sure why it's not highlighted the string same as 2 blocks up

```javascript
function some(JavaScript, "code"){}
```

I can guess the second half issue is because I used `JavaScript` above and `javascript` below. I actually came here to propose and possibly implement that being case insensitive. Funny though, in my installation of discourse I get the opposite behavior. `JavaScript` has less highlighting than `javascript`.
