  * 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()

  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.
