I've noticed in 100.1 that, sometimes, using the mouse wheel to zoom will cause the map to pan instead.  Has anyone else seen this?  It seems to happen most often when the map hasn't finished rendering yet.

I finally took some time to look closer at this at 100.5, and it was a feedback occurring due to a two-way binding with the map scale.  The fix was simple.  UPDATE: I've attached a simpler example project duplicating the issue.

I've seen similar behavior in SetViewpointAsync [WPF]: the map will pan to the center of the geometry instead of zooming to it.  It happens rarely, and I haven't been able to reproduce it consistently, but it is annoying when it happens.
