Expected Behavior

this inside class A should be preserved after commonjs transformation.

When running npm run exec:dev, the output is 1.

Actual Behavior

this inside class A is transformed into commonjsGlobal.

When running npm run exec:build, an error is thrown.

Additional Information

The check here is heuristic. It does not check for the case of class.
