Call stack for one of the crashes.

A few months ago, we had a fairly consistent crash on one of our pages that downloads many files. At the time, we were using Xamarin Forms 1.5, so we held off investigation since we were planning on an update to 2.x.

That upgrade happened, and now we're on 2.1.0. The crash has reappeared. The call stack (attached) suggests the renderer gets confused and holds on to a reference to a widget that's gone. I haven't been able to reproduce it myself, but a remote QA team member has seen it several times on an iPad Air 2.

Should be fixed in 2.3.4-pre1. Thank you!
