Can someone explain how dockview magically "unmounts" and "mounts" a component and still preserve state?

Genuinely like curious about this. This is technically a SolidJS component that I'm using for the panels. I'm not sure how it magically persists the SolidJS state in there even when it unmounts/mounts the same component from the DOM, when I switch tabs.

The usual technique to persist state even after unmounting/mounting a component is to lift the state up a component tree.

I know I'm just using dockview-core for this, and not completely SolidJS so there's no component tree in terms of the dock view, but is the component actually being removed from the DOM at all? Because it seems like it does for me.

Can someone explain the magic?
