then isn't the question.. When did you become aware of it and why hasn't it been on the known issues list?
The idea of those known issue lists being in part to let us the customer know what you are or have scheduled to work on so we don't keep reporting it as a new issue and flooding your already overloaded CS staff with new reports.
Personally I think that particular posting should be updated almost daily as you find and mark things, instead it always seems like random listing of some bugs just to show you noticed things were not perfect.
I got infraction for this kind of post made by myself, so watch it.
It looks like their incompetence to put a known issue into the list of other known issues is preventing them to read as well.
