In connection with the display of synonyms on the glossary pane, I encountered a similar, but somewhat different bug in Ichiro.
This <br> appears only when a Find operation is done. The regular glossary matching is working perfectly (as below).
This entry is not a duplicate. It is the last added one with the latest build of Ichiro.
Entries added after it are OK.
So, I deleted this entry and added it anew. It's OK now.
