🚀 Summary

🤖 Generated by Copilot at 9c5f143

Added support for nested Drawer components with proper z-index values. This involved adding a new test case in Drawer.test.tsx and using a custom hook and context in Drawer.tsx.

• Implement z-index accumulation for nested Drawer components (link, link, link, link, link)

• Import useZIndex hook and zIndexContext from ../_util (link, link)
• Wrap Drawer component with zIndexContext.Provider and pass context z-index value to children (link)
• Pass z-index value generated by useZIndex hook to RcDrawer component (link)
• Add test case for nested Drawer components with Select components inside them (link, link)
  • Import Select component from antd (link)
  • Render three levels of Drawer components, each with a Select component (link)
