Description

Description

When using a borderColor and borderBottomColor with different values on the same View:

Expected result: 3 borders have the borderColor color, and 1 has the borderBottomColor color.

Actual result (on Android, with RN 0.72): the 4 borders have the borderColor color.

This seems to be a regression from RN 0.71.8, where the issue is not present.

React Native Version
