Actually I believe it is a bug in closures externs from which elemental2 is generated. Without checking my guess is that IDBDatabase is annotated with a @constructor tag rather than a @interface which is incorrect as the spec defines it as an interface [1]. Unfortunately, this is a common problem with some of the closure compiler externs. It does not impact people using closure compiler. Unfortunately, the jsinterop-generator will generate incorrect code if the extern is incorrectly annotated.

But they do accept fixes for these kind of things?

I believe that they would. My limited experience is that they will almost always accept changes that improve the correctness unless it requires massive reworks of internal apps. Even then I have got through some compromise changes to externs that achieve the same thing. Sometimes the occasional ping is required to get the ball rolling but other than that a relatively smooth experience to get changes in.
