In bug 130727, I made it WebProcess responsibility to cancel composition on selection change. I thought that this didn't change iOS behavior, because we had this under PLATFORM(COCOA) in WebPageProxy.
But turns out that WebPageProxy::cancelComposition had a no-op implementation on iOS, unlike of the new WebProcess one.
