1) (in the admin) The WYSIWUG field does not stop the parent container from stopping resizing when min-width point is passed. So, make a field (where you can press buttons to style input) then go to add that field to a post, try to change the browser width to like 200px. The parent of the window will continue to resize passed the point when its child (the WYSIWUG box) stopped re-sizing.
This is not really a bug:
2) Image field that shows in the admin the URL needs a bit CSS styling, at least added top margin. Maybe better a border, padding, light background and some text color to make it a bit more pretty (similar to the scheme of other fields). Maybe like a disabled input=text style...
