Actually, I think it is; if this is removed, forcing the the test to fail (by commenting out the fix) doesn't manifest because External dependency "@parcel/transformer-react-refresh-wrap" is not declared in package.json.

This was a tough one to track down because it often 'failed' silently,
and when it did produce a symptom at build time, it looked like a scope hoisting bug:
The error would only occur when:
in a way that required deep symbol resolution in the packaging step.
For a while, the working theory was that there was an issue in symbol resolution because the last condition would result in the build failure. But the underlying problem was actually the combination of the first two conditions.
The issue can be summarized as:
Testing
One integration test was added:
yarn test:integration --grep "refresh.*library"Additionally, reproductions involving library targets from all of the linked issues were resolved with this fix.
