Hello @GreenSock Jack or somebody else who could help met with this,
For a while now I'm using webpack together with the gsap npm package and uglifyjs.
I keep things up to date and so far everything was working fine, until today.
After updating the gsap package from 1.20.4 to 1.20.6 suddenly uglifyJs starts complaining.
I only updated gsap, so only the gsap module has changed.
I just found out gsap 1.20.4 works fine, and the problem starts with gsap 1.20.5:
