[insinfo]

ngdart

Which operating system(s) does this bug appear on?

Windows

Which browser(s) does this bug appear on?

Chrome 117.0.5938.132 64 bits

Is this a regression?

No

Description

I am accepting these warnings when I run webdev build or "dart run build_runner build" I copied the lib pdfjs 3.11.174 in the web folder to be able to use it in my project and I saw that it is parsing CSS files, is there a way to ignore these warnings so that the angular don't parse them

Please provide the steps to reproduce the bug

Create a simple project with ngcli and unzip the pdfjs lib in the web folder

Please provide the exception or error you saw
