Mehdi Mulani 97153d68cf Guard against bad values set in RCTCustomScrollView
Summary:
UIScrollView's internal logic with scroll indicator dies when bad values (e.g. NaN/Infinity) are set on the position/size.
We already guard UIManager with these checks but the RCTScrollView's underlying scrollview (RCTCustomScrollView) can get these set from other places, and we're seeing crashes in this area.
