Title: 0.23 Bugfixes: (#34591729) Ensure element is removed once from the scene and its modifiers are not called after that

Includes test.

Removing is now improved with checking if element is not rendering now, so removing it immediately.

If fact, may _not_ fix the bug, needs additional investigation.
