Thanks @marillat for forwarding me the report, much appreciated!

This is because the various textes are stored as HTML to keep the formatting.
The text is correctly saved, but the issue appears when loading and parsing it.

The fix is to correctly escape text when saving it.
For already stored recipes, the breaking characters should be escaped when loading the text, and properly saving it on the next save.

This is indeed a major issue and I will work on it next.
