Steps to reproduce:

I added `<blockquote>` and (inline) `<code>` tags to content.


Actual results:

There was no initial indication that these would not be permitted, until I saved the content. Then, the undermentioned appeared:

> Your post has been changed because invalid HTML was found in the message body. The invalid HTML has been removed. Please review the message and submit the message when you are satisfied.

Although the `<blockquote>` tags initially remained within the content subsequent to the refresh that displayed that message, the `<code>` tags were immediately redacted, with no way to recover the content.

When I saved the edited content to be submitted to the moderators for approval, the `<blockquote>` markup was silently redacted.


Expected results:

Basic formatting, like `<blockquote>` and `<code>` should be supported. The latter, especially so, since `<pre>` is!
