Bug description

While using WYSIWYG editor, emoticons on pretext show as letter, e.g. "i" for info emoticon (see screenshots).
However, the final pages shows the emoticon after all.

Steps to reproduce

self-explanatory

Relevant log output

none

This is: Insertion of the information emoticon seems to fail on pretext because the emoticon's background is missing, leaving only the letter "i" behind. The final page works fine because the emoticon's own background renders. Non-letter emoticons seem to be fine.
