Subject: [PATCH] Fix initialization when calling from other Worker
window global is not defined when Tesseract gets called from another worker.
Also, when blob-type is not defined, it fails with an error like:
'Refused to execute script from 'blob:http://localhost:8080/160d4c2a-...-7af01' because its MIME type ('') is not executable.'
