[api-minor] Make the popup independent of their associated annotations

- it'll help to be able to move popups on screen to let the user read the text
- popups won't inherit some properties from their parent:
  - the popup can be misrendered if for example the parent has a clip-path property.
- add an outline to the popup when the parent is focused.
- hide a popup when it's clicked.
