WYSIWYG Editor Bugs on Digg

Here are a few bugs I've experienced so far with the editor

1. Placeholder in body doesn't go away when typing certain things, such as starting a list or pasting

2. Selecting all (ctrl+a), then pressing backspace not only clears the body, but the audience, title and block

3. Selecting all (ctrl+a) in the body selects more data than the body

4. Pasting a body with three line breaks into a new post populates the title with the first line

5. Editing markdown is difficult
