Allow Hover AND Click together

I went through the same situation, and I think it's absurd that this discussion is still ongoing after three years. I came to the same conclusions as you did to create this workaround, but I’ll describe my case as well. I needed this button to take me to another frame, which has a button that takes the user back to the original frame. I had set it up with Click > New Frame and While Pressing > Tooltip, but the tooltip blocked the click action from working.
 

What I did in another situation was simply place the click action inside a hover interaction. I believe the ideal solution would be to have a proper tooltip component and always add it to the elements that need hover tooltips. Like in this video, but you can also make the tooltip a component: 

Hope this helps somehow now with UI3. Abraços!
