Content jumps when scrolling on iOS

[AntonPalmqvist]

I'm seeing content jumps when scrolling up on iOS 18 in the Elk PWA 0.17.3 running on an Iphone Pro 15.
It's fine when I scroll down, but when I start scrolling upwards the content starts jumping around.
I'm not seeing this on desktop.

I know there was a similar bug reported recently that was supposedly fixed in 0.17.3, but it didn't fix it on iOS it seems.

I'm also frequently experiencing this issue, in Elk 0.17.3 and since 0.17.0 (which is when I started using it).

This is happening on both mobile and desktop for me:
Android 16: latest stable Firefox and Vivaldi
iOS 26
Linux Ubuntu 24.04 (KDE, Wayland): latest stable Firefox and Vivaldi

Haven't tested on other browsers, happy to if that would help.
