Quick reply + editor placeholders

[Xon]

Affected version

2.2.10 Patch 1

The quick reply macro (public:quick_reply_macros:body) has a deferred argument which hides most of the html in a way which looks to prevent content reflows. However it doesn't work in threads when clicking the 'reply' button on a post.

The following javascript error is logged:

       Uncaught TypeError: Cannot read properties of null (reading 'bbCode')
