Nothing in the code expects things to be on the left/right, it was just a naming convention. However, it caused some issues because CSSJanus flips the attributes in the stylesheet for RTL languages. So just use more descriptive names that also avoid issues with RTL languages. Bug: T290731 Change-Id: I8a383cd1e3981dc8a826ff60eee523d9f71d1d3d
