💡 Background and solution
Anchor onClick handler does not respect preventDefault, currently it always call scrollTo. But, if the target anchor is hidden (e.g. collapsed), if I want to first expand it, then scroll to, currently there is no way to avoid the scrollTo jumping since AnchorLink always calls scrollTo after onClick, does not check whether the event isDefaultPrevented().
With this PR, now user can do their own logic in the onClick, without the default scrollTo behavior.
