LGTM generally. Would you mind adding a single simple test for this at the end of the unit tests in this file?

Perhaps render a list with 10 items inside a scrollview that is 5 high?

[joshka]

LGTM. Thanks for the PR. Will merge once ci runs.

The broken checks were unrelated to this PR (another crate uses f64::midpoint which was stabilized in rust 1.85, and the current MSRV of the crate is 1.80)
