As originally described in bug 1527511:

UpdateMinimumScaleSize() is sizing the layout viewport based on the XMost() and YMost() of the scrollable overflow rect, rather than its width and height.

On RTL scrollframes, that can result in a layout viewport that's too small.

There is a potential fix posted to bug 1527511.
