When a user clicks on an interaction, we should check whether we have already tracked the impression as the content must be visible now for sure. If the impression was not tracked before we should track it. Just in case we did not detect the impression became visible etc.

Note: There can be a scroll or timer event that detects the same content became visible as well. This would not be a problem since we do not track same content block twice unless trackPageView was called. This allows us to simple track a content impression when an interaction is happening.

Short or mid term. As it is probably easy to implement maybe rather short term.
