zIndex isn't working

[ethanyuwang]

(Describe your issue in detail.)

Environment

Environment:
OS: macOS High Sierra 10.13.1
Node: 8.9.4
Yarn: Not Found
npm: 5.6.0
Watchman: 4.9.0
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: 3.0 AI-171.4443003

Packages: (wanted => installed)
react: 16.2.0 => 16.2.0
react-native: 0.53.0 => 0.53.0

Expected Behavior

The top card should overlay on top of the bottom card.

Actual Behavior

The top card starts below the bottom card, as zIndex has no effect

Steps to Reproduce

I defined a top card with zIndex of 1, and the other card with zIndex of 0. However, the top card simply
renders below the bottom card, with no overlap.

This doesn't seem like a zIndex issue - the views are not overlapping.
