Created attachment 486530 [details]
Example book

Description of problem:

When an admonition has a title set but that title is hidden by a remark tag the admonition title bar does not render correctly. If the hidden title had not been included at all a default title would have been used (for example Note) and thus this rendering issue would have been avoided.

Have tested in publican default and publican-redhat brands (see attached for example book).


Version-Release number of selected component (if applicable):

2.5

How reproducible:

Every time.

Steps to Reproduce:
1. Create an admonition with a title.
2. Add <remark> tags around the title (within the <title> tags)
3. Build the book.
4. View the admonition in both pdf and html views.
  
Actual results:

No admonition header bar is displayed, text and image alignment is off.

Expected results:

Default title, in my example book 'Note'.

Additional info:

The attached book contains an example of this behaviour in chapter 1 - have included both source and built output.
