Summary: State updates can be batched together idependent of `this.state`, so we should do any calculation deriving state from state within a `setState()` callback. This fixes a bug where we were relying on potentially stale state, a RenderMask derived from `this.state` instead of the `state` callback parameter, when triggering updates from focus. Note that this is not exercised on Android/iOS, but it on desktop/web. I noticed this a while back while making another change, but that change got abandoned, so this is the independent fix.
