Mac Catalyst only. What a horizontal collectionview does with the vertical mouse wheel:
'always' scrolls horizontally, 'never' leaves it to the parent, 'auto' (default) scrolls horizontally
unless an ancestor scroll view can scroll vertically.
Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overriden by subclasses to provide accurate and efficient measurement of their contents.
When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an exception, thrown by measure(int, int).
Parameters
widthMeasureSpec: number
horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
heightMeasureSpec: number
vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
Used on iOS to auto update cells size if the cell request a layout change (like image itemLoading). Experimental and true by default
