[8.2.x][ES2015][prod] custom decorators on inputs are ignored when used inside lib聽#15325
Description
馃悶 bug report
Affected Package
I'd assume @angular-devkit/build-angular@0.802.x
Is this a regression?
Yes, the issue was not present in Angular 8.1.x or 8.0.x, or even previous majors.
Description
When running in prod mode, with a ES2015 target, any custom decorator that is used in a library used by the app will simply be ignored.
馃敩 Minimal Reproduction
I made a small repository that reproduces the issue. You can follow the README.
Basically, what it does is:
- build a library that uses a custom decorator on a component's input
- use the component from that built library in an app, in prod mode, with a ES2015 target
=> the decorator is ignored
