Visual appearance of Table in DragAndDropWrapper

I have a default Window (with VerticalLayout) with a Table component, wrapped in a DragAndDropWrapper. I want to drop a csv/excel file from the deskop file system into the vaadin table and start the import of it. This works great!
However, i have one issue: the visual appearance (see attached file): the table’s right scroll bar does not have enough space. Is this a bug or is my code wrong?

Table table = new Table();
table.setWidth(“100%”);
table.setPageLength(25);

// TableDropBox extends DragAndDropWrapper
TableDropBox dropBox = new TableDropBox(table); // width = 100%
window.addComponent(dropBox);
