ReactPDF memory leak reproduction

leaktest.js

const React = require("react")
const ReactPDF = require("@react-pdf/renderer").default

const { Document, Page, Text } = ReactPDF

function Component() {
  return React.createElement(
    Document,
    null,
    React.createElement(
      Page,
      { size: "A4" },
      // keep this line
      React.createElement(Text, null, "Hello"),
    ),
  )
}

async function go(n) {
  for (let i = 1; i <= n; i++) {
    // await ReactPDF.renderToStream(React.createElement(Component))
    await ReactPDF.render(React.createElement(Component), `out/${i}.pdf`)
    const memoryUsage = process.memoryUsage().heapUsed / (1 << 20)
    console.log(JSON.stringify({ i, memoryUsage }))
  }
}

go(1000)

  },

Run yarn test and see memoryUsage going up with each render.
