Webpack + React 17 fails to compile on any of the following because webpack
complains that `startTransition` doesn't exist in `React`:
* import { startTransition } from "react"
* import * as React from from "react";
  "startTransition" in React ? React.startTransition(() => setState()) : setState()
* import * as React from from "react";
  "startTransition" in React ? React["startTransition"](() => setState()) : setState()

Moving it to a constant such as the following solves the Webpack/React 17 issue:
* import * as React from from "react";
  const START_TRANSITION = "startTransition";
  START_TRANSITION in React ? React[START_TRANSITION](() => setState()) : setState()
777
However, that introduces webpack/terser minification issues in production builds
in React 18 where minification/obfuscation ends up removing the call of
React.startTransition entirely from the first half of the ternary.  Grabbing
this exported reference once up front resolves that issue.
