• I am using the latest React Native version

This is actually a reopen of my #16878 issue. I've got some thumbs up, so I think I am not the only one with this issue. This time I updated my example project to a pure rn project with the latest release (rn Branche)

Environment

    npmGlobalPackages:
      react-native-cli: 2.0.1
      react-native-git-upgrade: 0.2.7

Steps to Reproduce

1. Make a list (FlatList or Array.map, it happens with both)
2. The renderItem should get an onPress event
3. The onPress event changes the style to a high zIndex and position absolute

Expected Behavior

I expect that the component with the high zIndex is over every other component.

Actual Behavior

It seems like it ignores the zIndex property. The behavior is exactly like I would not apply any zIndex. I can remove the zIndex and I get the same result.
