When creating a code block in markdown with trailing line feeds, it displays correctly in edit mode, but after saving the edit I can briefly see it the same way, then the last line disappears.
Example:
This Python quine has a trailing new line. In edit mode, it displays, but not after that on https://codegolf.stackexchange.com/. It displays fine here, for some reason. Also, I'm fairly certain it used to work, as I've used blocks like these several times, but I just saw this bug today.
Markdown:
<pre><code>_='_=%r;print _%%_\n';print _%_
</code></pre>
Displayed:
_='_=%r;print _%%_\n';print _%_
In case the post linked above is changed later, I took some screenshots:
After saving edit:
Notes:
- I tested this with Firefox, Chrome, Opera, and IE 11.
- This bug doesn't occur in Firefox, but occurs in the others.
- The "flicker" from correct to wrong only happens in Chrome and Opera.
