When loading pdfjs we got this error:
Uncaught TypeError: Class constructor PDFViewer cannot be invoked without 'new' at new j (custom-elements-es5-adapter.js:4) at TemplateInstance._stampTemplate (shared_8.html:1119) at TemplateInstance._stampTemplate (shared_8.html:2473) at TemplateInstanceBase (shared_8.html:5093) at TemplateInstance.klass (shared_8.html:5176) at new TemplateInstance (shared_8.html:5305)
Seems related to the way in which we transpile those sources.
