Issue: Reattaching same Angular element causes `Shadow root cannot be created on a host which already hosts a shadow tree`
Labels: area: elements

### Which @angular/* package(s) are the source of the bug?

elements

### Is this a regression?

No

### Description

I'm trying to reuse the same custom Angular element I created. I created an element class with `createCustomElement()`, added it to the list of custom elements, created the element and rendered it with `appendChild`. The element rendered and worked fine.

Then I removed the element from the DOM and rendered it again in the same place (I didn't create a new element). Now the element rendered, but lost some styles and doesn't respond to events anymore (I just added show/hide button inside there for testing).

For the main component of the element I used `ViewEncapsulation.ShadowDom`. So when the element renders for the third time (not the second!) I get the error `Shadow root cannot be created on a host which already hosts a shadow tree.`. If I set the main component to `ViewEncapsulation.Emulate` (the default), there is no error, but the element still behaves incorrectly and loses styles.

It is clear why the error occurs only on the third render: this is due to the [mechanism](https://github.com/angular/angular/blob/92f30a749d676a290f5e173760ca29f0ff85ba8c/packages/elements/src/component-factory-strategy.ts#L138) that allows not to destroy the component if it was moved in the DOM (if `DESTROY_DELAY` did not pass between the destruction and the call).

It is also clear why the element does not work correctly after re-rendering. Angular Elements completely kills the component after it was removed from the DOM (with `DESTROY_DELAY` delay). This element can no longer be used, and its re-rendering (`connectedCallback` function) leads to errors.

I think it is strange that the element can no longer be used after it was removed from the DOM. Regular HTML elements don't behave like that. I can remove and place an element as many times as I want, and it will work correctly. If I try to place the same element twice, then by default it will be removed from the previous place and added to the new one.

I need to use the element after it is removed from the DOM, because it stores its current state (I make tabs in my application). Yes, I can bypass the removal from the DOM and use `hidden`, but I would not like to resort to such a crutch.

There are two buttons in the reproduction:
- Toggle web component — adds or removes a web component (appendChild, removeChild). It generates errors.
- Toggle — a button inside an Angular element, which is only needed to check that the component responds to events.
