1. Open deviantart.com on mobile for the first time (or use incognito, or whatever)
2. *As soon as* it's visible, tap on the "person" icon in the upper right, ideally to open the login panel
3. A native app banner pops down from the top, and steals the tap (even though I'm *very* sure I'm tapping before it's visible) redirecting you to the Play Store and just all-around producing a terrible experience

I think in this case, the banner is either present but invisible, or we just haven't rendered it. Either way, it's a case for not triggering clicks on things that just changed in some way.
