What steps will reproduce the problem?
1. Create a Raid (I did Ulduar 10 man)
2. Fill out raid details and Create the event with a multi-line description that forces the description text input area to scroll.
3. On a new day Create the same Raid so that it will attempt to auto-fill the details

What is the expected output? What do you see instead?
All future events will now start with the details text input area scrolled and no option to scroll up to the first line. Even with a blank description, when you begin to type a new description it will be hidden (scrolled out of the viewable area)

What version of the product are you using?
5.0b2

Do you have an error log of what happened?
No error reported.
