Closes #33463 (closed) and Closes #33579 (closed)
Since the bootstrap is not changing the default value of the elementContext option, changing the value of the altBoundary option is not needed for any modifier in real. By default, the value for elementContext is 'popper' which means the boundary context will be checked for the popper element by default. Setting the altBoundary to true in the flip modifier will change this behavior and then boundary context will be checked for reference element (means button element).
Doing so will require setting the value for the boundary option manually. That is not needed in real (at least for the tooltips when these are appended to the body).
See the discussion here: https://github.com/twbs/bootstrap/issues/33463#issuecomment-822352640
/CC @XhmikosR to add this in the next release if seems good.
