Grid layout bug

### Description

When using a Grid layout as a cell layout for my table it breaks the rendering on one line, as you can see in the image below: (look at the Run Monitor line)

Even if I remove the problematic line, the rendering issue will happening on another line. (Look at Selector line)

Also, the `Label.LineBreakMode` property is not being respected.
### Steps to Reproduce

1. Run this project: https://github.com/pictos/GridLayoutIssue
2. See the layout break
