Bug report

Summary

A strange indent appears at the bottom of the page when you click on the “Help” button. Apparently it has something to do with the pop-up window.

It was reported earlier by @phantomphondler here - #16056 (comment)

Environment

MODX 3.1.0-dev

Hi, i saw the same behavior in many places in admin panel on MODX 3.0.4, and it looks like specificity how ExtJS on manager page calculate window's positions. The bottom section on the screenshot was filled DevTools panel, and then DevTools was closed, right?

But i cant reproduce it in MODX2, therefore it looks like the interface bug (related to window size changes and ExtJS recalculation i think)

@dimasites As far as I can see, the problem is in overflow: hidden; for .x-viewport body, but maybe I'm wrong.
