[Bug] GridLength of 0 no longer hides/clips grid row content

Description

Setting the height of a grid row to an absolute size of 0 no longer properly hides/clips the composite control content in that row. I validated that this is a bug in XF 4.2.0.848062 and is still broken in 4.3.0.851321-pre3. This used to work in XF 3.4.0.1008975.

Steps to Reproduce

1. Create a composite control (e.g. containing a label and an image)
2. Add the composite control to a grid row
3. Programmatically set the height of the grid row to 0 absolute.

Expected Behavior

The composite control content within the grid row is hidden.

Actual Behavior

The composite control content within the grid row is partially visible.
