* DoLayout did not work as expected, after the call
the scrollbars would have an 1px offset inside the target
* the target needs to be resized while setting a new border, otherwise
it would overlap the border and give some drawing artefacts
- I'm still unsure if the behavior change introduced with the layout stuff is nice
