Here is something you can try for yourself, if you have a WordPress blog. When I do this, I get an odd UI experience:
- In your blog, start a new post.
- Go to the “Visual” tab
- Clique the dropdown box arrow, next to where it says “Paragraph”
- Scroll the page.
When I do this, the right hand column that contains “Change Status”, “Tags & Categories” and the rest scrolls and so does the dropdown list. I don’t know if this is something easily solved, or even known about. I think it is amusing, and mostly harmless.
