// 2. webpack defaultRules issues (fixable with https://github.com/webpack/webpack/issues/8412#issuecomment-445586591)

// We should explore this at a later date.

// tesseract has a bug where broken image URLs will silently fail. We could spawn a new worker
// every time to work around the issue, but then it literally spawns a new web worker for each request,
// which seems excessive. So we just live with the bug for now.
