Detailed description and rationale

The text orientation buttons are oversized and not spaced. They also sit above the vertically stacked label instead of aligning alongside it.

Code pointers

We may need to apply custom padding to these buttons to ensure consistent sizing and proper alignment instead of using the padding set on ui-toggle button
