A separate outer span with the title text needs to be added because:
(1) The default bootstrap popover behavior takes the title as the
popover title, if provided.
(2) We need to avoid having the title area be too big in the
me_message template.
Fixes#12769.

While we could fix this issue by changing the markdown processor,
doing so is not a robust solution, because even a momentary bug in the
markdown processor could allow cached messages that do not follow our
security policy.
This change ensures that even if our markdown processor has bugs that
result in rendered content that does not properly follow our policy of
using rel="noopener noreferrer" on links, we'll still do something
reasonable.

There may be a deeper issue that various JavaScript logic expects
every message to have a `.message_content` element, but we definitely
should have the `.rendered_markdown` class on any markdown content.
Fixes#13634.
