Selectable Android text takes touch focus. React Native then scrolls focused children using untransformed coordinates, which moves inverted timelines even though the user did not scroll.\n\nSkip that auto-scroll only for touch-focused, selectable, non-editable text in inverted vertical scroll views, preserving normal focus navigation and editable inputs.
