Current behavior:
https://github.com/ionic-team/stencil/blob/master/BREAKING_CHANGES.md#import--h--is-required

Expected behavior:
Improvements coming in TypeScript 4.1 may allow us to remove this requirement via a configuration item in the tsconfig.json as such:

{
  "compilerOptions": {
    "jsx": "react-jsx",
    "jsxImportSource": "@stencil"
  }
}

Investigate this further when TS 4.1 is available.
