Summary:
This issue is found when investigating T101563978 with IOS platform. When animation is off, the x position measurement is off after `scrollToItem` is called.
The android fix is checked in at D31492685 (1a9e2d5d55). For IOS, the correct state data is updated only for animated cases, but not for instant scroll cases. This diff unified them.
Changelog
[IOS][Fixed] Fixed an edge case when scroll to item/index is called without animation, the offset position is not updated. This caused the measurement of the position to be wrong.
