Inputs don't map to correct property when bindingPropertyName is used.

[shelbyd]

Given

class Parent {
  inputs = {
    foo: 'foo',
  };
}

@Component()
class Child {
  @Input('foo') bar: string;
}

Expected

Child component has property bar set to 'foo'.

Actual

Child component has property foo set to 'foo'.

Hi, thanks for reporting this.

Yes, this use-case actually was never supported, and nobody even used it thus far =)

I have an idea how it can be fixed (using information about component's IO from it's ComponentFactory) but for right now do not have access to laptop so won't be able to implement a fix.

If you want to submit a PR with the fix please feel free to do so.
And if you have any questions let me know.

Fix released in v2.1.0
