Now I have all the information I need. Let me create a comprehensive report:\n\nModal Component Analysis Report\n\nFile Location\nMain Modal component: /Users/USER/workspace/doctolib/oxygen/packages/core/src/overlays/Modal/Modal.tsx\n\n---\n\n1. How Modal Handles Rendering When isOpen is False\n\nThe Modal uses Material-UI's Modal component wrapped with a Portal-based approach and conditional mounting. Here's the rendering logic:\n\nThe Modal passes the show prop d\n…(truncated, 3015 more chars)\n\n★ Insight ─────────────────────────────────────\nThe Modal uses a hybrid mounting strategy: children live in the DOM during transitions (to animate out smoothly), but are fully unmounted (return null) once the exit animation completes. This is a common pattern where keeping children mounted just long enough for the exit animation avoids a jarring \"disappear immediately\" effect while still freeing DOM resources after close.\n─────────────────────────────────────────────────\n\nAnswer: No — children are NOT rendered in the DOM when the modal is closed.\n\nThe Modal uses conditional mounting logic:\n\n// From the inlined react-overlays Modal\nconst mountModal = show || (Transition && !this.state.exited)\nif (!mountModal) {\n  return null\n}\n\nFull lifecycle:\n\n| State | Children in DOM? | How |\n|---|---|---|\n| isOpen={true} | Yes | Mounted, CSS opacity: 1 |\n| isOpen={false} (transition running) | Yes (temporary) | CSS exit animation (~300ms) |\n| isOpen={false} (after transition) | No | Returns null, fully unmounted |\n\nSo children are temporarily kept mounted only during the exit animation (for a smooth fade-out), then fully removed from the DOM. This means:\n- No hidden DOM bloat when modal is closed\n- Child components are destroyed and lose their state on close (re-initialized on next open)\n- Any expensive child component (e.g. a form, a video) will re-mount fresh each time the modal opens",
