Mohamed Boudra 63923fdd07 Keep Android timeline still when tapping text (#4090)
* fix(android): keep timeline still when tapping text

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.
