The contents of the <note> elements (green rounded rectangles) moves down when the window's width is increased, with the increment being bigger than some undetermined value (that is, changing the window's size just a bit won't display the issue). This doesn't happen when the window width is decreased, either.

Formerly axr/core#85

@shviller Can we verify whether this still occurs?
