Current behavior

Using withDefaults work fine when using the jit, but when built with aot those defaults are ignored.

Expected behavior

The defaults provided in withDefaults should be used with both jit and aot compilation.

Angular version:

4.2.5

ng2-tag-input version:

1.4.6

I am using the latest angular 9 and the latest version of ngx-chips, trying to globally configure the default theme:

TagInputModule.withDefaults({ tagInput: { theme: "ddf"}});

and the ts compiler says "ddf is not assignable to type "" .
