Late follow-up from the discussion this morning, here is the logic we use on iOS. Completely forgot we have a minHeight too: TimelineMediaFrame.swift

I confirm that a screenshot from an iPhone 13 is not fully rendered in the timeline on EXA. It is normal to protect the rendering in the timeline.

Let's align Android with iOS as a minimum.

We need design feedback on https://github.com/element-hq/element-x-android/pull/1941
