Bikeshed artifacts in comments in examples

[rakuco]

https://w3c.github.io/window-management/#basic-example has something that looks like this in index.bs:

```js
[...]
// Detect when the current `ScreenDetailed` or an attribute thereof changes.
screenDetails.addEventListener('currentscreenchange', onCurrentScreenChange);

The rendered version looks like this though:

// Detect when the current <code data-opaque bs-autolink-syntax='`ScreenDetailed`'>ScreenDetailed</code> or an attribute thereof changes.
screenDetails.addEventListener('currentscreenchange', onCurrentScreenChange);

This is the case for all JS comments including backquotes.
