Yes there are few bugs related to ComboBox.
I think we can fix JDK-8090221 separately. The issue JDK-8279139, which is closed as duplicate of this issue is fixed, but changing the test slightly shows another issue which is mentioned in JDK-8263942. Since we have different scenarios like these, we can fix these issue with these PRs one by one. So I believe other issues can be fixed separately.
