After the refactor performed on 3fea5b213 to start using OWL, a lot of
aria attributes were lost.
ARIA attributes are required to ensure good compatibility with asistive
technologies and keyboard users.
This commit reintroduces such attributes, which include:
- `aria-label`: used for elements with title but no text
- `role`: mainly used for elements that behaves as buttons or links
- `aria-expanded`: used on buttons that toggle menus or content, e.g.
button to open attachments or followers
- And another ones like `aria-pressed`, `tabindex`, etc
