Code highlights prevent the placeholder value from being displayed in a codeblock

I struggled with this issue for the last days before figuring out what the issue was. It was reported here: Placeholder Forms - #48 by jericson.

The issue doesn’t seem to happen (anymore?) on the example given in the linked post, so I’ll do my own repro here:

[wrap=placeholder key=TABLE description="table name" default="users"][/wrap]

```
SELECT * FROM =TABLE=;
```

does:

SELECT * FROM =TABLE=;

The variable isn’t recognized because of the codeblock highlight, which is automatically set to SQL.

The output HTML is:

<code class="hljs language-sql" data-highlighted="yes">
  <span class="hljs-keyword">SELECT</span>
  <span class="hljs-operator">*</span>
  <span class="hljs-keyword">FROM</span>
  <span class="hljs-operator">=</span>
  <span class="hljs-keyword">TABLE</span>
  <span class="hljs-operator">=</span>
  ;
</code>

If I specify txt in the codeblock, then the value is correctly displayed:

SELECT * FROM =TABLE=;

The expected behavior would be to have the value displayed regardless of the code highlight.

I don’t know why the codeblock isn’t automatically set to SQL as it was the case yesterday. It renders my repro ineffective, but it works on try.discourse.org so here’s a screenshot:

Regardless of the auto language detection, the fact is that some language highlights will break the string =VALUE= and the value won’t be rendered, which is unwanted.
