I am a firefox user. I have the same issue in Edge and Chrome.
I tested some more and looks like if I filter on DVD or Blu-ray it works fine with sometimes a small glitch where it is behind other elements the first time.
It also happens when I search for a movie, for example ‘Wrong Again’ and then go up with the arrow keys.
With that I was able to reproduce at least the issue without the filter bar being on, and I’m sure that will point our developers to fix this for the other situations too.
