The poster and title are too high in mobile mode

[Slinet6056]

Describe the bug
My Jellyfin server version is 10.8.9. I'm having this problem when using the official Jellyfin client on my Android tablet. Also I found that if I manually change the display mode to mobile in the web client, this problem also occurs. And it is normal if narrowing the browser width or on mobile. Also the backdrop doesn't show up on the title page, I'm not sure if it's a bug or not.

To Reproduce

@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/presets/kaleidochromic_preset.css');

This problem also exists under the other two presets.
