Fix tooltip offset when using Bootstrap > 5.3 (#2119)

This was caused by this upstream change: twbs/bootstrap@d533e6f

The fix causes tooltips to be slightly positioned wrong for Bootstrap >= 5 and < 5.3. We decided to accept that trade-off. React Bootstrap has done the same: react-bootstrap/react-bootstrap#6622
