Why are there so many scrollbars on the Editor page? (DNN7)

At a quick glance, all of the following have inline height set:

BrowserSetTab

SettingsBox

MainSetTab etc

What is the reasoning for this?
Very simple reason because the settings page for the editor provider is mainly accessible as popup window, which you access from the link bellow the editor. In that case it looks much better with scrolling only the settings instead of the whole page. Of course it's a different case on the actually settings page in the host menu, but because its an clone of the popup I kept the same look.
