Gridlayout is stupid (or me)

I've had horrible experiences with this framework, I just don't understand where these spacings between the lines of my grid come from.

The report provides only a screenshot, a description of unexpected grid spacing, and dependency versions; it names no repository file, test, or reproducible layout. Start by identifying the GridLayout markup and styles from the attached example, then reproduce the spacing with the listed NativeScript and Angular versions. Done means the spacing cause is isolated and the expected layout behavior is documented or verified.
