Research direction

Start by reproducing the warning with rc-drawer@4.2.0, rc-util@5.6.6, React 17.0.1, and React DOM 17.0.1, then trace where switchScrollingEffect reaches a DOM element in the utility package. Done means the warning no longer appears while the drawer's scrolling behavior remains intact.

Description

Warning: Warning: React does not recognize the switchScrollingEffect prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase switchscrollingeffect instead. If you accidentally passed it from a parent component, remove it from the DOM element.
