[gabrieldonadel]

Test Plan

1. Open the RNTester app and navigate to the Transforms page
2. Check the transform style through the Transform using a string section

@necolas should we use yellowboxes even though we only show this error when running on DEV mode? We also do this inside the _validateTransforms function, should we update that as well?
