Hi samsiervo,
Document widgets allow users to visualize different types of contents. The behaviour you are finding is due to the possibility to hide part of the content. For example, if you have a table with a lot of rows, probably, you don't want to see them at the same time but you prefer to have a widget with little dimensions and with the possibility to scroll. At the moment, there's no possibility to disable this behabiour. Alternatively you can adjust document widget to the minimun height and width such that scroll bars don't be displayed.
Regards,
Alberto
