r43114: committed fix for modal overlay issue, setting the exact width and height.
The rectangles can still be seen for a fraction of a second when displaying the spinners, but this only happens on Chrome desktop when using the view manager. It doesn't happen on any other browser or mobile devices, and it doesn't happen on Chrome desktop when the component is outside the view manager. No matter what technique I tried, the rectangles were still visible for a short instant. It has to do with how the opacity gets applied to the overlay on Chrome desktop, and there's nothing that can be done at the moment (without making big, risky changes to the component).
