Description

Describe the bug The dropdown is not deleted after each switching page with Vue-Router. Therefore multiple dropdown are maintain on the page.

To Reproduce

  1. I use append-to-body and :calculate-position="withPopper" as in the guide : Dropdown position
  2. When I use the select, a listbox is created
  3. I change the page, return back and reuse the same select
  4. A new listbox is created

Expected behavior Create and use one dropdown

Research direction
Investigate the component lifecycle hooks (e.g., beforeDestroy/unmounted) to ensure any dropdown elements appended to body are removed on component unmount. Check if Vue Router navigation triggers proper cleanup. No maintainer comments or PRs exist, so the fix likely involves adding a cleanup mechanism in the component.
