[WYSIWYG] Extra back slash in code block

It seems to happen in comment box. Let's try:

```py class MediaWikiProvider(OAuth2Provider): id = "mediawiki" name = "MediaWiki" account_class = MediaWikiAccount oauth2_adapter_class = MediaWikiOAuth2Adapter ```

Hi,

I couldn’t reproduce this on our end. The latest Quire version is 1681, could you try again and see if the issue persists?

If it does, please share a screen recording so our team can look into it further.

Ah, found the reason, in the comment box, if we start as Markdown code, the issue will happen. If we start by using one of Quire commands, the issue won't happen.

class MediaWikiProvider(OAuth2Provider):
    id = "mediawiki"
    name = "MediaWiki"
    account_class = MediaWikiAccount
    oauth2_adapter_class = MediaWikiOAuth2Adapter

Yes, it is fixed.
