ConstraintLayout

• Fixed #572: Vertical margin and gone margin of chains not applied

• androidx.constraintlayout.compose.layoutId tag parameter is now null by default, so it’s interchangeable with androidx.compose.ui.layout.layoutId

MotionLayout

• Fixed: Not reflecting child size changes cause by recomposition
• Gone<->Visible components are now animated as expected
• Disabled an internal debugging flag that affected runtime performance
