run npm test,
touch the __tests__/a.spec.js file to get the test running,
observe a correctly reported exception line,
uncomment the second line of the test file to let Babel transform the import.
save the file,
observe an incorrectly reported exception line.

It does happen only in watch mode. After restarting, the error is displayed correctly.
