Closes #18871

LGTM! SImple and neat solution.

Thank you very much for your work on this issue. 👍
To avoid any misunderstandings; Our primary use case from #18871 is extraction of i18n tokens from libraries in node_modules and not from "local" libraries.
Due to my limited understanding of the extractor, I cannot discern if this would be handled with this solution.

This works for both local and node_modules libraries.

@petebacondarwin @alan-agius4 are you planning to merge this for a 10.1.x patch too?

[alan-agius4]

@santam85, No this feature will not be back ported to v10.
