Issues and Steps to Reproduce
- Run the code below
- Uncomment the line of 'YGNodeSetMeasureFunc', run again.
Expected Behavior
Expected the child node's width should be 282.
{layout: {width: 282, height: 200, top: 0, left: 0}, flexDirection: 'column', alignItems: 'stretch', alignContent: 'stretch', flexGrow: 0, flexShrink: 0, flexBasis: nan%, overflow: 'hidden', width: nan%, height: 200pt, children: [
{layout: {width: 282, height: 200, top: 0, left: 0}, flexDirection: 'column', alignItems: 'stretch', alignContent: 'stretch', alignSelf: 'stretch', flexGrow: 0, flexShrink: 0, flexBasis: nan%, overflow: 'hidden', padding: 100pt, width: nan%, height: nan%, },
]},
Actual Behavior
Get different calculation results while set 'YGNodeSetMeasureFunc' or not even if the function was never invoked actually both cases.
{layout: {width: 282, height: 200, top: 0, left: 0}, flexDirection: 'column', alignItems: 'stretch', alignContent: 'stretch', flexGrow: 0, flexShrink: 0, flexBasis: nan%, overflow: 'hidden', width: nan%, height: 200pt, children: [
{layout: {width: 200, height: 200, top: 0, left: 0}, flexDirection: 'column', alignItems: 'stretch', alignContent: 'stretch', alignSelf: 'stretch', flexGrow: 0, flexShrink: 0, flexBasis: nan%, overflow: 'hidden', padding: 100pt, width: nan%, height: nan%, },
]},
