How does a Portal maintain the parent-child relationship in terms of events, even if it renders children outside the parent DOM hierarchy?
- Portals automatically attach the portal content to the parent component's DOM hierarchy.
- Portals rely on the browser's native event handling mechanisms to maintain event relationships.
- Portals use a custom event system to simulate the parent-child event relationship.
- Portals use event bubbling and capture phases to propagate events from the portal content to its parent component, preserving the relationship.
Portals maintain parent-child event relationships by leveraging event propagation through event bubbling and capture phases. When an event occurs within the portal content, it bubbles up to the parent component, allowing you to handle events seamlessly as if the content were still within the parent DOM hierarchy. Portals don't use a custom event system, automatic attachment to the parent DOM, or browser-native mechanisms to achieve this.
