Bullet point lists with colored EOL get badly formatted

When a bullet point list has line ending with wolored fonts, they get screwed up after being edited with the wysiwig editor.

here's an exemple to copy/paste in the "source" editor. Save and visualize it, it's ok. Then open it in the WYSIWIG editor and save => the output will be different.

* task1            (% style="color: rgb(255, 0, 0);" %)3j/h(%%)
** subtask1.1             1j/h    
* task2            (% style="color: rgb(255, 0, 0);" %)1j/h
* task3            (% style="color: rgb(255, 0, 0);" %)DONE
