Unescaping new inline code cells inside code blocks is not working correctly.

This happens in both engines. Minimal reprex:

Input	Output
--- engine: jupyter keep-md: true --- ``` This doesn't unescape: `{{python}} 1.2` This evaluates: `{python} 1.2` ```	--- engine: jupyter keep-md: true --- ``` This doesn't unescape: `{{python}} 1.2` This evaluates: 1.2 ```
--- engine: knitr keep-md: true --- ``` This doesn't unescape: `{{r}} 1.2` This evaluates: `{r} 1.2` ```	--- engine: knitr keep-md: true --- ``` This doesn't unescape: `{{r}} 1.2` This evaluates: 1.2 ```

It's very hard to write about the feature in this case.

This bug only happens inside non-executable code cells.

There's a pretty ugly workaround, which is to use Unicode zero-width spaces in the code cells that need to not be executed.
