On the bug report page, I wrote this comment:
This report indicates a problem with Tiki version 19.x. If that's correct, that this is the Tiki version being used, I recommend updating the test site to the most recent version, Tiki 20.1. There have been a lot of fixes and enhancements so the WYSIWYG fade problems might have been fixed.
Also, I suggest using the comment feature on that page rather than discussing here in the forums, although I understand your desire to get this issue on people's radar.
