Not shown SpringIndicator.Refresher() when a header exists in tableView and collectionView.

[fxwx23]

Thank you for your great work and library in beforehand.

Now, I'm facing a problem that SpringIndicator.Refresher() doesn't work when tableView (or collectionView) has header like
tableView.tableHeaderView = customHeaderView
or
collectionView.registerNib(UINib(nibName: "CustomHeaderReusableView", bundle: nil), forSupplementaryViewOfKind:UICollectionElementKindSectionHeader, withReuseIdentifier: CustomHeaderReusableView.reuseIdentifier).

How can I fix this problem? Any Ideas?
I want SpringIndicator.Refresher() work as same as UIRefreshControl() does.

It did not consider the tableHeaderView.
Thanks.
