Missing part of the content when using exclamation marks

To reproduce this error follow this steps:

1. Create an issue
2. On the field description put this code : Look at this! Hello, look at this picture!
3. Create a template to export the wiki:description. Could you see the template here
4. Only catch the first text and put the image. Could you see the template generated here

It works when we make a linebreak after each sentence.
