* data('bs.popover') is not a jQuery data anymore
-> fetch data from the instance instead.
* use the new class name 'popover-arrow' instead of 'arrow'
* website_forum: offset is not a number anymore
-> Convert to string instead.
* BS5 event listener: 'focus' -> 'focusin'
* use `mouseover` event to show and `mouseout` to hide.
* disable at some point the animation to avoid remaining listener
in the DOM.
