There are multiple ways in which you can specify how the panel renders.

https://dockview.dev/docs/core/panels/rendering

Options exist for multiple cases:

1. Where you never want the elements DOM position to move (`always` rendering mode) and the HTMLElement is simply hidden (display: none) when not visible. 2. Where you only want the DOM element to exist when the panel is visible (`onlyWhenVisible` mode)

In the case of React the React Tree is always maintained in either mode.
