Nested QML Layout Sizing Confusion

[stickabee]

I'm trying to use Layouts to size Rectangle areas containing many sets of Label:Control pairs. I was trying to have a ScrollView in which there are several nested GridLayouts. When two of the Gridlayouts are next to each other, the smaller of the two seems to be driving the determination of the GridLayout row height, resulting in pairs of controls being clipped out of the view. I'll include a picture that more clearly demonstrates this (See the bottom of "Section 1", below):

How would I size that GridLayout row to the LARGER of the two GridLayouts, still using Layouts instead of something with an explicit size.

Thanks for any help you can provide!
