What happened?

Similarly the already fixed #882, this error only occurs in unit test, and not breaking that, just a log message, and i only observed if the problematic component has multiple unit test. If you have at least 4, than it is observable easily. I observed this bug with both the IxSelect component and the IxDropdown as well. My reasoning why this is an issue is also the same as the previous fixed issue.
